 ## Terminal.Gui Coding Style
 
-**Terminal.Gui** follows the [Mono Coding Guidelines](https://www.mono-project.com/community/contributing/coding-guidelines/). [`/.editorconfig`](https://github.com/gui-cs/Terminal.Gui/blob/b0a43ba338adf5ec069066e5a7dff8fea39b41db/.editorconfig) enforces this style in Visual Studio. Use `Ctrl-K-D` in Visual Studio to have it reformat code.
+**Terminal.Gui** uses a derivative of the [Microsoft C# Coding Conventions](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions), with any deviations from those (somewhat older) conventions codified in the .editorconfig for the solution, as well as even more specific definitions in team-shared dotsettings files, used by ReSharper and Rider.\
+Before you commit code, please run the formatting rules on **only the code file(s) you have modified**, in one of the following ways, in order of most preferred to least preferred:
+
+ 1. `Ctrl-E-C` if using ReSharper or Rider
+ 2. Running the free [CleanupCode](https://www.jetbrains.com/help/resharper/CleanupCode.html) tool from JetBrains (this applies the same formatting rules as if you had used ReSharper or Rider, but is free for all users, if you don't have a license for those products)
+     - Run at the command line, from the solution root directory, as: `cleanupcode.exe relative/path/to/your/file.cs`
+ 3. If you are unable to use either of those options, the last resort is to use `Ctrl-K-D` in Visual Studio (with default C# developer key bindings), to apply the subset of the formatting rules that Visual Studio can apply.

+# CommunityToolkit.MVVM Example
+
+This small demo gives an example of using the `CommunityToolkit.MVVM` framework's `ObservableObject`, `ObservableProperty`, and `IRecipient<T>` in conjunction with `Microsoft.Extensions.DependencyInjection`. 
+
+Right away we use IoC to load our views and view models.
+
+``` csharp
+// As a public property for access further in the application if needed. 
+public static IServiceProvider Services { get; private set; }
+...
+// In Main
+Services = ConfigureServices ();
+...
+private static IServiceProvider ConfigureServices ()
+{
+    var services = new ServiceCollection ();
+    services.AddTransient<LoginView> ();
+    services.AddTransient<LoginViewModel> ();
+    return services.BuildServiceProvider ();
+}
+```
+
+Now, we start the app and get our main view.
+
+``` csharp
+Application.Run (Services.GetRequiredService<LoginView> ());
+```
+
+Our view implements `IRecipient<T>` to demonstrate the use of the `WeakReferenceMessenger`. The binding of the view events is then created.
+
+``` csharp
+internal partial class LoginView : IRecipient<Message<LoginAction>>
+{
+    public LoginView (LoginViewModel viewModel)
+    {
+        // Initialize our Receive method
+        WeakReferenceMessenger.Default.Register (this);
+        ...
+        ViewModel = viewModel;
+        ...
+        passwordInput.TextChanged += (_, _) =>
+                                     {
+                                         ViewModel.Password = passwordInput.Text;
+                                         SetText ();
+                                     };
+        loginButton.Accept += (_, _) =>
+                              {
+                                  if (!ViewModel.CanLogin) { return; }
+                                  ViewModel.LoginCommand.Execute (null);
+                              };
+        ...
+        // Let the view model know the view is intialized.
+        Initialized += (_, _) => { ViewModel.Initialized (); };
+    }
+    ...
+}
+```
+
+Momentarily slipping over to the view model, all bindable properties use some form of `ObservableProperty` with the class deriving from `ObservableObject`. Commands are of the `RelayCommand` type. The use of `ObservableProperty` generates the code for handling `INotifyPropertyChanged` and `INotifyPropertyChanging`.
+
+``` csharp
+internal partial class LoginViewModel : ObservableObject
+{
+    ...
+    [ObservableProperty]
+    private bool _canLogin;
+
+    private string _password;
+    ...
+    public LoginViewModel ()
+    {
+        ...
+        Password = string.Empty;
+        ...   
+        LoginCommand = new (Execute);
+
+        Clear ();
+
+        return;
+
+        async void Execute () { await Login (); }
+    }
+    ...
+    public RelayCommand LoginCommand { get; }
+
+    public string Password
+    {
+        get => _password;
+        set
+        {
+            SetProperty (ref _password, value);
+            PasswordLengthMessage = $"_Password ({_password.Length} characters):";
+            ValidateLogin ();
+        }
+    }
+```
+
+The use of `WeakReferenceMessenger` provides one method of signaling the view from the view model. It's just one way to handle cross-thread messaging in this framework.
+
+``` csharp
+...
+private async Task Login ()
+{
+    SendMessage (LoginAction.LoginProgress, LOGGING_IN_PROGRESS_MESSAGE);
+    await Task.Delay (TimeSpan.FromSeconds (1));
+    Clear ();
+}
+
+private void SendMessage (LoginAction loginAction, string message = "")
+{
+    switch (loginAction)
+    {
+        case LoginAction.LoginProgress:
+            LoginProgressMessage = message;
+            break;
+        case LoginAction.Validation:
+            ValidationMessage = CanLogin ? VALID_LOGIN_MESSAGE : INVALID_LOGIN_MESSAGE;
+            ValidationColorScheme = CanLogin ? Colors.ColorSchemes ["Base"] : Colors.ColorSchemes ["Error"];
+            break;
+    }
+    WeakReferenceMessenger.Default.Send (new Message<LoginAction> { Value = loginAction });
+}
+
+private void ValidateLogin ()
+{
+    CanLogin = !string.IsNullOrEmpty (Username) && !string.IsNullOrEmpty (Password);
+    SendMessage (LoginAction.Validation);
+}
+...
+```
+
+And the view's `Receive` function which provides an `Application.Refresh()` call to update the UI immediately.
+
+``` csharp
+public void Receive (Message<LoginAction> message)
+{
+    switch (message.Value)
+    {
+        case LoginAction.LoginProgress:
+            {
+                loginProgressLabel.Text = ViewModel.LoginProgressMessage;
+                break;
+            }
+        case LoginAction.Validation:
+            {
+                validationLabel.Text = ViewModel.ValidationMessage;
+                validationLabel.ColorScheme = ViewModel.ValidationColorScheme;
+                break;
+            }
+    }
+    SetText();
+    Application.Refresh ();
+}
+```

+# Terminal.Gui C# SelfContained
+
+This project aims to test the `Terminal.Gui` library to create a simple `native AOT` `self-container` GUI application in C#, ensuring that all its features are available.
+
+With `Debug` the `.csproj` is used and with `Release` the latest `nuget package` is used, either in `Solution Configurations` or in `Profile Publish` or in the `Publish_linux-x64` or in the `Publish_osx-x64` files.
+Unlike self-contained single-file publishing, native AOT publishing must be generated on the same platform as the target execution version. Therefore, if the target execution is Linux, then the publishing must be generated on a Linux operating system. Attempting to generate on Windows for the Linux target will throw an exception.
+
+To publish the `native AOT` file in `Debug` or `Release` mode, it is not necessary to select it in the `Solution Configurations`, just choose the `Debug` or `Release` configuration in the `Publish Profile` or the `*.sh` files.
+
+When executing the file directly from the `native AOT` file and needing to debug it, it will be necessary to attach it to the debugger, just like any other standalone application and selecting `Native Code`.

-***The current, stable, release of Terminal.Gui is [v1.x](https://www.nuget.org/packages/Terminal.Gui). It is stable, rich, and broadly used. The team is now focused on designing and building a significant upgrade we're referring to as `v2`. Therefore:***
- * *`v1` is now in maintenance mode, meaning we will accept PRs for v1.x (the `develop` branch) only for issues impacting existing functionality.*
- * *All new development happens on the `v2_develop` branch. See the V2 discussion [here](https://github.com/gui-cs/Terminal.GuiV2Docs/discussions/1940).*
- * *Developers are encouraged to continue building on [v1.x](https://www.nuget.org/packages/Terminal.Gui) until we announce `v2` is stable.*
-
+* The current, stable, release of Terminal.Gui v1 is [![Version](https://img.shields.io/nuget/v/Terminal.Gui.svg)](https://www.nuget.org/packages/Terminal.Gui).
+* The current `prealpha` release of Terminal.Gui v2 can be found on [Nuget](https://www.nuget.org/packages/Terminal.Gui).
+* Developers starting new TUI projects are encouraged to target `v2`. The API is signifcantly changed, and significantly improved. There will be breaking changes in the API before Beta, but the core API is stable.
+* `v1` is in maintenance mode and we will only accept PRs for issues impacting existing functionality.

+
+## Sample Usage in C#
+
+The following example shows a basic Terminal.Gui application in C#:
+
+```csharp
+// This is a simple example application.  For the full range of functionality
+// see the UICatalog project
+
+// A simple Terminal.Gui example in C# - using C# 9.0 Top-level statements
+
+using System;
+using Terminal.Gui;
+
+Application.Run<ExampleWindow> ().Dispose ();
+
+// Before the application exits, reset Terminal.Gui for clean shutdown
+Application.Shutdown ();
+
+// To see this output on the screen it must be done after shutdown,
+// which restores the previous screen.
+Console.WriteLine ($@"Username: {ExampleWindow.UserName}");
+
+// Defines a top-level window with border and title
+public class ExampleWindow : Window
+{
+    public static string UserName;
+
+    public ExampleWindow ()
+    {
+        Title = $"Example App ({Application.QuitKey} to quit)";
+
+        // Create input components and labels
+        var usernameLabel = new Label { Text = "Username:" };
+
+        var userNameText = new TextField
+        {
+            // Position text field adjacent to the label
+            X = Pos.Right (usernameLabel) + 1,
+
+            // Fill remaining horizontal space
+            Width = Dim.Fill ()
+        };
+
+        var passwordLabel = new Label
+        {
+            Text = "Password:", X = Pos.Left (usernameLabel), Y = Pos.Bottom (usernameLabel) + 1

+
+        var passwordText = new TextField
+        {
+            Secret = true,
+
+            // align with the text box above
+            X = Pos.Left (userNameText),
+            Y = Pos.Top (passwordLabel),
+            Width = Dim.Fill ()
+        };
+
+        // Create login button
+        var btnLogin = new Button
+        {
+            Text = "Login",
+            Y = Pos.Bottom (passwordLabel) + 1,
+
+            // center the login button horizontally
+            X = Pos.Center (),
+            IsDefault = true
+        };
+
+        // When login button is clicked display a message popup
+        btnLogin.Accept += (s, e) =>
+                           {
+                               if (userNameText.Text == "admin" && passwordText.Text == "password")
+                               {
+                                   MessageBox.Query ("Logging In", "Login Successful", "Ok");
+                                   UserName = userNameText.Text;
+                                   Application.RequestStop ();
+                               }
+                               else
+                               {
+                                   MessageBox.ErrorQuery ("Logging In", "Incorrect username or password", "Ok");
+                               }
+                           };
+
+        // Add the views to the Window
+        Add (usernameLabel, userNameText, passwordLabel, passwordText, btnLogin);
+    }

+## Development and Design-Time PowerShell Modules
+This directory contains PowerShell modules for use when working with Terminal.sln
+
+### Purpose
+These modules will be modifed and extended as time goes on, whenever someone decides to add something to make life easier.
+
+### Requirements
+These modules are designed for **PowerShell Core, version 7.4 or higher**, on any platform, and must be run directly within a pwsh process.\
+If you want to use them from within another application, such as PowerShell hosted inside VSCode, you must first run `pwsh` in that terminal.
+
+As the primary development environment for Terminal.Gui is Visual Studio 2022+, some functionality may be limited, unavailable, or not work on platforms other than Windows.\
+Most should still work on Linux, however.\
+Functions which are platform-specific will be documented as such in their Get-Help documentation.
+
+Specific requirements for each module can be found in the module manifests and will be automatically imported or, if unavailable, PowerShell will tell you what's missing.
+
+### Usage
+From a PowerShell 7.4 or higher prompt, navigate to your Terminal.Gui repository directory, and then into the Scripts directory (the same directory as this document).
+
+#### Import Module and Configure Environment
+Run the following command to import all Terminal.Gui.PowerShell.* modules:
+```powershell
+Import-Module ./Terminal.Gui.PowerShell.psd1
+```
+If the environment meets the requirements, the modules will now be loaded into the current powershell session and exported commands will be immediately available for use.
+
+#### Getting Help
+All exported functions and commandlets are provided with full PowerShell help annotations compatible with `Get-Help`.
+
+See [The Get-Help documentation at Microsoft Learn]([https://](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/get-help?view=powershell-7.4)) for Get-Help information.
+
+#### Cleaning Up/Resetting Environment
+No environment changes made by the modules on import are persistent.
+
+When you are finished using the modules, you can optionally unload the modules, which will also reset the configuration changes made on import, by simply exiting the PowerShell session (`exit`) or by running the following command:\
+**NOTE DIFFERENT TEXT FROM IMPORT COMMAND!**
+```powershell
+Remove-Module Terminal.Gui.PowerShell
+```

+  .SYNOPSIS
+  Resets changes made by ConfigureEnvironment.pst to the current PowerShell environment.
+  .DESCRIPTION
+  Optional function to undo changes to the current session made by ConfigureEnvironment.ps1.
+  Changes only affect the current session, so exiting will also "reset." 
+  .PARAMETER Exit
+  Switch parameter that, if specified, exits the current PowerShell environment.
+  Does not bother doing any other operations, as none are necessary.
+  .INPUTS
+  None
+  .OUTPUTS
+  None
+  .EXAMPLE
+  Reset-PowerShellEnvironment
+  To undo changes in the current session.
+  .EXAMPLE
+  Reset-PowerShellEnvironment -Exit

+# Terminal.Gui C# SelfContained
+
+This project aims to test the `Terminal.Gui` library to create a simple `self-contained` `single-file` GUI application in C#, ensuring that all its features are available.
+
+With `Debug` the `.csproj` is used and with `Release` the latest `nuget package` is used, either in `Solution Configurations` or in `Profile Publish`.
+
+To publish the self-contained single file in `Debug` or `Release` mode, it is not necessary to select it in the `Solution Configurations`, just choose the `Debug` or `Release` configuration in the `Publish Profile`.
+
+When executing the file directly from the self-contained single file and needing to debug it, it will be necessary to attach it to the debugger, just like any other standalone application. However, when trying to attach the file running on `Linux` or `macOS` to the debugger, it will issue the error "`Failed to attach to process: Unknown Error: 0x80131c3c`". This issue has already been reported on [Developer Community](https://developercommunity.visualstudio.com/t/Failed-to-attach-to-process:-Unknown-Err/10694351). Maybe it would be a good idea to vote in favor of this fix because I think `Visual Studio for macOS` is going to be discontinued and we need this fix to remotely attach a process running on `Linux` or `macOS` to `Windows 11`.

+// HACK:
+// WindowsANSIConsole/Terminal has two issues:
+// 1) Tearing can occur when the console is resized.
+// 2) The values provided during Init (and the first WindowsANSIConsole.EventType.WindowBufferSize) are not correct.
+//
+// If HACK_CHECK_WINCHANGED is defined then we ignore WindowsANSIConsole.EventType.WindowBufferSize events
+// and instead check the console size every every 500ms in a thread in WidowsMainLoop. 
+// As of Windows 11 23H2 25947.1000 and/or WT 1.19.2682 tearing no longer occurs when using 
+// the WindowsANSIConsole.EventType.WindowBufferSize event. However, on Init the window size is
+// still incorrect so we still need this hack.

+# Proposed Design for a modern Cursor system in v2
+
+See end for list of issues this design addresses.
+
+## Tenets for Cursor Support (Unless you know better ones...)
+
+1. **More GUI than Command Line**. The concept of a cursor on the command line of a terminal is intrinsically tied to enabling the user to know where keybaord import is going to impact text editing. TUI apps have many more modalities than text editing where the keyboard is used (e.g. scrolling through a `ColorPicker`). Terminal.Gui's cursor system is biased towards the broader TUI experiences.
+
+2. **Be Consistent With the User's Platform** - Users get to choose the platform they run *Terminal.Gui* apps on and the cursor should behave in a way consistent with the terminal.
+
+## Lexicon & Taxonomy
+
+- Cursor - A visual indicator to the user where keyboard input will have an impact. There is one Cursor per terminal sesssion.
+- Cursor Location - The top-left corner of the Cursor. In text entry scenarios, new text will be inserted to the left/top of the Cursor Location. 
+- Cursor Size - The width and height of the cursor. Currently the size is limited to 1x1.
+- Cursor Style - How the cursor renders. Some terminals support various cursor styles such as Block and Underline.
+- Cursor Visibilty - Whether the cursor is visible to the user or not. NOTE: Some ConsoleDrivers overload Cursor Style and Cursor Visibility, making "invisible" a style. Terminal.Gui HIDES this from developers and changing the visibilty of the cursor does NOT change the style.
+- Caret - Visual indicator that  where text entry will occur. 
+- Selection - A visual indicator to the user that something is selected. It is common for the Selection and Cursor to be the same. It is also common for the Selection and Cursor to be distinct. In a `ListView` the Cursor and Selection (`SelectedItem`) are the same, but the `Cursor` is not visible. In a `TextView` with text selected, the `Cursor` is at either the start or end of the `Selection`. A `TableView' supports mutliple things being selected at once.
+
+## Requirements
+
+- No flickering. The Cursor should blink/pulse at the rate dictated by the terminal. Typing, moving the mouse, view layout, etc... should not caue the cursor to flicker.
+- By default, the Cursor should not be visible. A View or View subclass should have to do anything (this is already the case) to keep the Cursor invisible.
+- Views that just want to show the cursor at a particular location in the Viewport should only have to:
+  - Optionally, declare a desired Cursor Style. Set `Application.CursorStyle`.
+  - Indicate the Cursor Locaiton when internal state dictates the location has changed (debatable if this should be in content or viewport-relative coords). Just set `this.CursorPosition`.
+  - To hide the cursor, simply set `this.CursorPostion` to `null`.
+- The Cursor should only be visible in Views where
+  - `Enabled == true`
+  - `Visible == true`
+  - `CanFocus == true`
+  - `this == SuperView.MostFocused`
+- If a `ConsoleDriver` supports Cursor Styles other than Default, they should be supported per-application (NOT View). 
+- Ensuring the cursor is visible or not should be handled by `Application`, not `View`.
+- General V2 Requirement: View sub-class code should NEVER call a `Driver.` API. Only `Application` and the `View` base class should call `ConsoleDriver` APIs; before we ship v2, all `ConsoleDriver` APIs will be made `internal`.
+
+## Design
+
+### `View` Focus Changes
+
+It doesn't make sense the every View instance has it's own notion of `MostFocused`. The current implemention is overly complicated and fragile because the concept of "MostFocused" is handled by `View`. There can be only ONE "most focused" view in an application. `MostFocused` should be a property on `Application`.
+
+* Remove `View.MostFocused`
+* Change all references to access `Application.MostFocusedView` (see `Application` below)
+* Find all instances of `view._hasFocus = ` and change them to use `SetHasFocus` (today, anyplace that sets `_hasFocus` is a BUG!!).
+* Change `SetFocus`/`SetHasFocus` etc... such that if the focus is changed to a different view heirarchy, `Application.MostFocusedView` gets set appropriately. 
+
+**MORE THOUGHT REQUIRED HERE** - There be dragons given how `Toplevel` has `OnEnter/OnLeave` overrrides. The above needs more study, but is directioally correct.
+
+### `View` Cursor Changes
+* Add `public Point? CursorPosition`
+    - Backed with `private Point? _cursorPosition`
+    - If `!HasValue` the cursor is not visible
+    - If `HasValue` the cursor is visible at the Point.
+    - On set, if `value != _cursorPosition`, call `OnCursorPositionChanged()`
+* Add `public event EventHandler<LocaitonChangedEventArgs>? CursorPositionChanged`
+* Add `internal void OnCursorPositionChanged(LocationChangedEventArgs a)`
+  * Not virtual
+  * Fires `CursorPositionChanged`
+
+### `ConsoleDriver`s
+
+* Remove `Refresh` and have `UpdateScreen` and `UpdateCursor` be called separately. The fact that `Refresh` in all drivers currently calls both is a source of flicker.
+
+* Remove the `xxxCursorVisibility` APIs and replace with:
+  * `internal int CursorStyle {get; internal set; }`
+    - Backed with `private int _cursorStyle`
+    - On set, calls `OnCursorStyleChanged()`
+  * Add `internal abstract void OnCursorStyleChanged()`
+    - Called by `base` whenever the cursor style changes, but ONLY if `value != _cursorStyle`.
+
+  * Add `internal virtual (int Id, string StyleName) []  GetCursorStyles()`
+    - Returns an array of styles supported by the driver, NOT including Invisible. 
+    - The first item in array is always "Default".
+    - Base implementation returns `{ 0, "Default" }`
+    - `CursesDriver` and `WindowsDriver` will need to implement overrides.
+
+  * Add `internal Point? CursorPosition {get; internal set; }`
+    - Backed with `private Point? _cursorPosition`
+    - If `!HasValue` the cursor is not visible
+    - If `HasValue` the cursor is visible at the Point.
+    - On set, calls `OnCursorPositionChanged` ONLY if `value != _cursorPosition`.
+  * Add `internal abstract void OnCursorPositionChanged()`
+    - Called by `base` whenever the cursor position changes. 
+    - Depending on the value of `CursorPosition`:
+        - If `!HasValue` the cursor is not visible - does whatever is needed to make the cursor invisible.
+        - If `HasValue` the cursor is visible at the `CursorPosition` - does whatever is needed to make the cursor visible (using `CursorStyle`).
+
+  * Make sure the drivers only make the cursor visible (or leave it visible) when `CursorPosition` changes!
+
+### `Application`
+
+* 
+
+* Add `internal static View FocusedView {get; private set;}` 
+  - Backed by `private static _focusedView`
+  - On set, 
+    - if `value != _focusedView` 
+        - Unsubscribe from `_focusedView.CursorPositionChanged`
+        - Subscribe to `value.CursorPositionChanged += CursorPositionChanged`        
+        - `_focusedView = value`
+        - Call `UpdateCursor` 
+
+* Add `internal bool CursorPositionChanged (object sender, LocationChangedEventArgs a)`
+
+    Called when:
+
+    - `FocusedView`
+        - Has changed to another View (should cover `FocusedView.Visible/Enable` changes)
+        - Has changed layout - 
+        - Has changeed it's `CursorPosition`
+    - `CursorStyle` has changed
+
+    Does:
+
+    - If `FocusedView is {}` and `FocusedView.CursorPosition` is visible (e.g. w/in `FocusedView.SuperView.Viewport`) 
+        - Does `Driver.CursorPosition = ToScreen(FocusedView.CursorPosition)`
+    - Else
+        - Makes driver cursor invisible with `Driver.CursorPosition = null`
+
+* Add `public static int CursorStyle {get; internal set; }`
+  - Backed with `private static int _cursorStyle
+  - If `value != _cursorStyle`
+    - Calls `ConsoleDriver.CursorStyle = _cursorStyle` 
+    - Calls `UpdateCursor`
+
+* Add `public (int Id, string StyleName) []  GetCursorStyles()`
+  - Calls through to `ConsoleDriver.GetCursorStyles()`
+
+
+
+# Issues with Current Design
+
+## `Driver.Row/Pos`, which are changed via `Move` serves two purposes that confuse each other:
+
+a) Where the next `AddRune` will put the next rune
+b) The current "Cursor Location"
+
+If most TUI apps acted like a command line where the visible cursor was always visible, this might make sense. But the fact that only a very few View subclasses we've seen actually care to show the cursor illustrates a problem:
+
+Any drawing causes the "Cursor Position" to be changed/lost. This means we have a ton of code that is constantly repositioning the cursor every MainLoop iteration.
+
+## The actual cursor position RARELY changes (relative to `Mainloop.Iteration`).
+
+Derived from abo`ve, the current design means we need to call `View.PositionCursor` every iteration. For some views this is a low-cost operation. For others it involves a lot of math. 
+
+This is just stupid. 
+
+## Flicker
+
+Related to the above, we need constantly Show/Hide the cursor every iteration. This causes ridiculous cursor flicker. 
+
+## `View.PositionCursor` is poorly spec'd and confusing to implement correctly
+
+Should a view call `base.PositionCursor`? If so, before or after doing stuff? 
+
+## Setting cursor visibility in `OnEnter` actually makes no sense
+
+First, leaving it up to views to do this is fragile.
+
+Second, when a View gets focus is but one of many places where cursor visibilty should be updated.

+# Dim.Auto Deep Dive
+
+The `Dim.Auto` type is a type of `Dim` that automatically sizes the view based on its content. This is useful when you want to size a view based on the content it contains. That content can either be the `Text`, the `SubViews`, or something else defined by the view.
+
+Like all `Dim` types, `Dim.Auto` is used to set the `Width` or `Height` of a view and can be combined with other `Dim` types using addition or subtraction (see. `DimCombine`).
+
+The `DimAutoStyle` enum defines the different ways that `Dim.Auto` can be used to size a view. The `DimAutoStyle` enum has the following values:
+
+* `Text` - The view is sized based on the `Text` property and `TextFormatter` settings.
+* `Content` - The view is sized based on either the value returned by `View.SetContentSize()` or the `Subviews` property. If the content size is not explicitly set (via `View.SetContentSize()`), the view is sized based on the Subview with the largest relvant dimension plus location. If the content size is explicitly set, the view is sized based on the value returned by `View.SetContentSize()`.
+* `Auto` -  The view is sized based on both the text and content, whichever is larger.
+
+## Using Dim.Auto
+
+`Dim.Auto` is defined as:
+
+```cs
+public static Dim Auto (DimAutoStyle style = DimAutoStyle.Auto, Dim minimumContentDim = null, Dim max = null)
+```
+
+To use `Dim.Auto`, set the `Width` or `Height` property of a view to `Dim.Auto (DimAutoStyle.Text)` or `Dim.Auto (DimAutoStyle.Content)`.
+
+
+For example, to create a `View` that is sized based on the `Text` property, you can do this:
+
+```cs
+View view = new ()
+{
+    Text = "Hello, World!",
+    Width = Dim.Auto (DimAutoStyle.Text),
+    Height = Dim.Auto (DimAutoStyle.Text),
+};
+```
+
+Note, the built-in `Label` view class does precisely this in its constructor.
+
+To create a `View` that is sized based on its `Subviews`, you can do this:
+
+```cs
+View view = new ()
+{
+    Width = Dim.Auto (DimAutoStyle.Content),
+    Height = Dim.Auto (DimAutoStyle.Content),
+};
+view.Add (new Label () { Text = "Hello, World!" });
+```
+
+In this example, the `View` will be sized based on the size of the `Label` that is added to it.
+
+### Specifying a miniumum size
+
+You can specify a minimum size by passing a `Dim` object to the `minimumContentDim` parameter. For example, to create a `View` that is sized based on the `Text` property, but has a minimum width of 10 columns, you can do this:
+
+```cs
+View view = new ()
+{
+    Text = "Hello, World!",
+    Width = Dim.Auto (DimAutoStyle.Text, minimumContentDim: Dim.Absolute (10)), // Same as `minimumContentDim: 10`
+    Height = Dim.Auto (DimAutoStyle.Text),
+};
+```
+
+Sometimes it's useful to have the minimum size be dynamic. Use `Dim.Func` as follows:
+
+```cs
+View view = new ()
+{
+    Width = Dim.Auto (DimAutoStyle.Content, minimumContentDim: Dim.Func (GetDynamicMinSize)),
+    Height = Dim.Auto (DimAutoStyle.Text),
+};
+
+int GetDynamicMinSize () 
+{
+    return someDynamicInt;
+}
+```
+
+### Specifying a maximum size
+
+It is common to want to constrain how large a View can be sized. The `maximumContentDim` parameter to the `Dim.Auto ()` method enables this. Like `minimumContentDim` it is of type `Dim` and thus can represent a dynamic value. For example, by default `Dialog` specifies `maximumContentDim` as `Dim.Percent (90)` to ensure a Dialog box is never larger than 90% of the screen.
+
+## Limitations
+
+`Dim.Auto` is not always the best choice for sizing a view. For example, if you want a view to fill the entire width of the Superview, you should use `Dim.Fill ()` instead of `Dim.Auto (DimAutoStyle.Content)`.
+
+`Dim.Auto` is also not always the most efficient way to size a view. If you know the size of the content ahead of time, you can set the `Width` and `Height` properties to `Dim.Absolute (n)` instead of using `Dim.Auto`.
+
+## Behavior of other Pos/Dim Types when used within a Dim.Auto-sized View
+
+The table below descibes the behavior of the various Pos/Dim types when used by subviews of a View that uses `Dim.Auto` for it's `Width` or `Height`:
+
+| Type        | Impacts Dimension | Notes                                                                                             |
+|-------------|-------------------|---------------------------------------------------------------------------------------------------------|
+| PosAlign    | Yes               | The subviews with the same `GroupId` will be aligned at the maximimum dimension to enable them to not be clipped. This dimension plus the group's position will determine the minimum `Dim.Auto` dimension. |
+| PosView     | Yes               | The position plus the dimension of `subview.Target` will determine the minimum `Dim.Auto` dimension. |
+| PosCombine  | Yes               | <needs clarification> |
+| PosAnchorEnd| Yes               | The `Dim.Auto` dimension will be increased by the dimension of the subview. |
+| PosCenter   | No                |  |
+| PosPercent  | No                |  |
+| PosAbsolute | Yes               |  |
+| PosFunc     | Yes               |  |
+| DimView     | Yes               | The position plus the dimension of `subview.Target` will determine the minimum `Dim.Auto` dimension. |
+| DimCombine  | Yes               | <needs clarification>  |
+| DimFill     | No                |  |
+| DimPercent  | No                |  |
+| DimAuto     | Yes               |  |
+| DimAbsolute | Yes               |  |
+| DimFunc     | Yes               | <needs clarification> |
+
+
+## Building Dim.Auto friendly View
+
+It is common to build View classes that have a natrual size based on their content. For example, the `Label` class is a view that is sized based on the `Text` property. 
+
+`Slider` is a good example of sophsticated Dim.Auto friendly view.
+
+Developers using these views shouldn't need to know the details of how the view is sized, they should just be able to use the view and have it size itself correctly.
+
+For example, a vertical `Slider` with 3 options may be created like this: which is size based on the number of options it has, it's orientation, etc... 
+
+```cs
+List<object> options = new () { "Option 1", "Option 2", "Option 3" };
+Slider slider = new (options)
+{
+    Orientation = Orientation.Vertical,
+    Type = SliderType.Multiple,
+};
+view.Add (slider);
+```
+
+Note the developer does not need to specify the size of the `Slider`, it will size itself based on the number of options and the orientation. 
+
+Views like `Slider` do this by setting `Width` and `Height` to `Dim.Auto (DimAutoStyle.Content)` in the constructor and calling `SetContentSize()` whenever the desired content size changes. The View will then be sized to be big enough to fit the content.
+
+Views that use `Text` for their content can just set `Width` and `Height` to `Dim.Auto (DimAutoStyle.Text)`. It is recommended to use `Height = Dim.Auto (DimAutoStyle.Text, minimumContentDim: 1)` to ensure the View can show at least one line of text.

-Terminal.Gui supports color on all platforms, including Windows, Mac, and Linux. The default colors are 24-bit RGB colors, but the library will gracefully degrade to 16-colors if the terminal does not support 24-bit color, and black and white if the terminal does not support 16-colors.
+Terminal.Gui provides a set of APIs for formatting text, line drawing, and character-based graphing. The fundamental concept is a [Cell](~/api/Terminal.Gui.Cell.yml) which ocupises a particular row and column in the terminal. A Cell includes the character (glyph) that should be rendred by the terminal, and attributes that indicate how the glphy should be rendered (e.g. the foreground and background color).
+
+Color is supported on all platforms, including Windows, Mac, and Linux. The default colors are 24-bit RGB colors, but the library will gracefully degrade to 16-colors if the terminal does not support 24-bit color, and black and white if the terminal does not support 16-colors.
+
+## View Drawing API
+
+A [View](~/api/Terminal.Gui.View.yml) will typically draw text when the [OnDrawContent](~/api/Terminal.Gui.View.yml#Terminal_Gui_View_OnDrawContent_) is called (or the `DrawContent` event is received).
+
+Outputting unformatted text involves:
+
+a) Moving the draw cursor using the `Move` API.
+b) Setting the attributes using `SetAttribute`.
+c) Outputting glyphs by calling `AddRune` or `AddStr`.
+
+Outputting formatted text involves:
+
+a) Adding the text to a [TextFormatter](~/api/Terminal.Gui.TextFormatter.yml) object.
+b) Setting formatting options, such as [TextFormatter.TextAlignment](~/api/Terminal.Gui.TextFormatter.TextAlignment.yml).
+c) Calling [TextFormatter.Draw](~/api/Terminal.Gui.TextFormatter.Draw.yml).
+
+Line drawing is accomplished using the [LineCanvas](~/api/Terminal.Gui.LineCanvas.yml) API:
+
+a) Add the lines via [LineCanvas.Add](~/api/Terminal.Gui.LineCanvas.Add.yml).
+b) Either render the line canvas via [LineCanvas.Draw](~/api/Terminal.Gui.LineCanvas.Draw.yml) or let the [View](~/api/Terminal.Gui.View.yml) do so automatically (which enables automatic line joining across Views).

+## Coordinate System for Drawing
+
+The [View](~/api/Terminal.Gui.View.yml) draw APIs, including the `OnDrawContent` method, the `DrawContent` event, and the [View.Move](~/api/Terminal.Gui.View.Move.yml) method, all take coordinates specified in *Viewport-Relative* coordinates. That is, `0, 0` is the top-left cell visible to the user.

-
-Every view has a focused view, and if that view has nested SubViews, one of those is 
-the focused view. This is called the focus chain, and at any given time, only one
-View has the [Focus](). 
-
-The library provides a default focus mechanism that can be used to navigate the focus chain. The default focus mechanism is based on the Tab key, and the Shift-Tab key combination
-
-Keyboard processing details are available on the [Keyboard Event Processing](keyboard.md) document.
-
-## Colors and Color Schemes
-
-All views have been configured with a color scheme that will work both in color
-terminals as well as the more limited black and white terminals. 
-
-The various styles are captured in the [Colors](~/api/Terminal.Gui.Colors.yml) class which defines color schemes for Toplevel, the normal views (Base), the menu bar, dialog boxes, and error UI::
-
-* `Colors.Toplevel`
-* `Colors.Base`
-* `Colors.Menu`
-* `Colors.Dialog`
-* `Colors.Error`
-
-You can use them for example like this to set the colors for a new Window:
-
-```
-var w = new Window ("Hello");
-w.ColorScheme = Colors.Error
-```
-
-ColorSchemes can be configured with the [Configuration and Theme Manager](config.md). 
-
-The [ColorScheme](~/api/Terminal.Gui.ColorScheme.yml) represents
-four values, the color used for Normal text, the color used for normal text when
-a view is focused an the colors for the hot-keys both in focused and unfocused modes.
-
-By using `ColorSchemes` you ensure that your application will work correctbly both
-in color and black and white terminals.
-
-Some views support setting individual color attributes, you create an
-attribute for a particular pair of Foreground/Background like this:
-
-```
-var myColor = Application.Driver.MakeAttribute (Color.Blue, Color.Red);
-var label = new Label (...);
-label.TextColor = myColor
-```

+## Tenets for Terminal.Gui Keyboard Handling (Unless you know better ones...)
 
 Tenets higher in the list have precedence over tenets lower in the list.
 
 * **Users Have Control** - *Terminal.Gui* provides default key bindings consistent with these tenets, but those defaults are configurable by the user. For example, `ConfigurationManager` allows users to redefine key bindings for the system, a user, or an application.
 
-* **More Editor than Command Line** - Once a *Terminal.Gui* app starts, the user is no longer using the command line. Users expect keyboard idioms in TUI apps to be consistent with GUI apps (such as VS Code, Vim, and Emacs). For example, in almost all GUI apps, `Ctrl-V` is `Paste`. But the Linux shells often use `Shift-Insert`. *Terminal.Gui* binds `Ctrl-V` by default.

+btn.KeyBindings.ReplaceKey (btn.KeyBindings.GetKeyFromCommands (Command.Accept));
 ```
 
 The [Command](~/api/Terminal.Gui.Command.yml) enum lists generic operations that are implemented by views. For example `Command.Accept` in a `Button` results in the `Clicked` event 
 firing while in `TableView` it is bound to `CellActivated`. Not all commands
 are implemented by all views (e.g. you cannot scroll in a `Button`). Use the `GetSupportedCommands()` method to determine which commands are implemented by a `View`. 
 
+Key Bindings can be added at the `Application` or `View` level. For Application-scoped Key Bindings see [ApplicationNavigation](~/api/Terminal.Gui.ApplicationNavigation.yml). For View-scoped Key Bindings see [Key Bindings](~/api/Terminal.Gui.View.yml#Terminal_Gui_View_KeyBinings).

 ### **[HotKey](~/api/Terminal.Gui.View.yml#Terminal_Gui_View_HotKey)** 
 
-A **HotKey** is a keypress that selects a visible UI item. For selecting items across `View`s (e.g. a `Button` in a `Dialog`) the keypress must have the `Alt` modifier. For selecting items within a `View` that are not `View`s themselves, the keypress can be key without the `Alt` modifier.  For example, in a `Dialog`, a `Button` with the text of "_Text" can be selected with `Alt-T`. Or, in a `Menu` with "_File _Edit", `Alt-F` will select (show) the "_File" menu. If the "_File" menu has a sub-menu of "_New" `Alt-N` or `N` will ONLY select the "_New" sub-menu if the "_File" menu is already opened.

If the "_File" menu has a sub-menu of "_New" `Alt+N` or `N` will ONLY select the "_New" sub-menu if the "_File" menu is already opened.
 
 By default, the `Text` of a `View` is used to determine the `HotKey` by looking for the first occurrence of the [HotKeySpecifier](~/api/Terminal.Gui.View.yml#Terminal_Gui_View_HotKeySpecifier) (which is underscore (`_`) by default). The character following the underscore is the `HotKey`. If the `HotKeySpecifier` is not found in `Text`, the first character of `Text` is used as the `HotKey`. The `Text` of a `View` can be changed at runtime, and the `HotKey` will be updated accordingly. [HotKey](~/api/Terminal.Gui.View.yml#Terminal_Gui_View_HotKey) is `virtual` enabling this behavior to be customized.

 # Layout
 
-Terminal.Gui v2 supports the following View layout systems (controlled by the [View.LayoutStyle](~/api/Terminal.Gui.LayoutStyle.yml)):
+Terminal.Gui provides a rich system for how `View` objects are laid out relative to each other. The layout system also defines how coordinates are specified.
 
-* **Absolute** - Used to have the View positioned exactly in a location, with a fixed size. Absolute layout is accomplished by constructing a View with an argument of type [Rect](~/api/Terminal.Gui.Rect.yml) or directly changing the `Frame` property on the View.
-* **Computed** - The Computed Layout system provides automatic aligning of Views with other Views, automatic centering, and automatic sizing. To use Computed layout set the 
- `X`, `Y`, `Width` and `Height` properties after the object has been created. Views laid out using the Computed Layout system can be resized with the mouse or keyboard, enabling tiled window managers and dynamic terminal UIs.
-* **Overlapped** - New in V2 (But not yet) - Overlapped layout enables views to be positioned on top of each other. Overlapped Views are movable and sizable with both the keyboard and the mouse.
+## Coordinates
 
-Examples:
+* **Screen-Relative** - Describes the dimensions and characteristics of the underlying terminal. Currently Terminal.Gui only supports applications that run "full-screen", meaning they fill the entire terminal when running. As the user resizes their terminal, the `Screen` changes size and the applicaiton will be resized to fit. *Screen-Relative* means an origin (`0, 0`) at the top-left corner of the terminal. `ConsoleDriver`s operate exclusively on *Screen-Relative* coordinates.
+* **Application-Relative** - The dimensions and characteristics of the application. Because only full-screen apps are currently supported, `Application` is effectively the same as `Screen` from a layout perspective. *Application-Relative* currently means an origin (`0, 0`) at the top-left corner of the terminal. `Applicaiton.Top` is a `View` with a top-left corner fixed at the *Application.Relative* coordinate of (`0, 0`) and is the size of `Screen`.
+* **Frame-Relative**  - The `Frame` property of a `View` is a rectangle that describes the current location and size of the view relative to the `Superview`'s content area. *Frame-Relative* means a coordinate is relative to the top-left corner of the View in question. `View.FrameToScreen ()` and `View.ScreenToFrame ()` are helper methods for translating a *Frame-Relative* coordinate to a *Screen-Relative* coordinate and vice-versa.
+* **Content-Relative** - A rectangle, with an origin of (`0, 0`) and size (defined by `View.GetContentSize()`) where the View's content exists. *Content-Relative* means a coordinate is relative to the top-left corner of the content, which is always (`0,0`). `View.ContentToScreen ()` and `View.ScreenToContent ()` are helper methods for translating a *Content-Relative* coordinate to a *Screen-Relative* coordinate and vice-versa.
+* **Viewport-Relative** - A *Content-Relative* rectangle representing the subset of the View's content that is visible to the user. If `View.GetContentSize()` is larger than the Viewport, scrolling is enabled. *Viewport-Relative* means a coordinate that is bound by (`0,0`) and the size of the inner-rectangle of the View's `Padding`. The View drawing primitives (e.g. `View.Move`) take *Viewport-Relative* coordinates; `Move (0, 0)` means the `Cell` in the top-left corner of the inner rectangle of `Padding`. `View.ViewportToScreen ()` and `View.ScreenToViewport ()` are helper methods for translating a *Viewport-Relative* coordinate to a *Screen-Relative* coordinate and vice-versa. To convert a *Viewport-Relative* coordinate to a *Content-Relative* coordinate, simply subtract `Viewport.X` and/or `Viewport.Y` from the *Content-Relative* coordinate. To convert a *Viewport-Relative* coordinate to a *Frame-Relative* coordinate, subtract the point returned by `View.GetViewportOffsetFromFrame`.
 
-```csharp
-// Absolute layout using a provided rectangle
-var label1 = new Label (new Rect (1, 1, 20, 1), "Hello")
+## The Frame
 
-// Computed Layout
-var label2 = new Label ("Hello") {
-    X = Pos.Right (label2),
+The `Frame` property of a `View` is a rectangle that describes the current location and size of the view relative to the `Superview`'s content area. The `Frame`  has a `Location` and `Size`. The `Location` describes the top-left corner of the view relative to the `Superview`'s content area. The `Size` describes the width and height of the view. The `Frame` is used to determine where the view is drawn on the screen and is used to calculate the Viewport and content size.
+
+## The Content Area
+
+ The content area is the area where the view's content is drawn. Content can be any combination of the `View.Text` property, `Subviews`, and other content drawn by the View. The `View.GetContentSize()` property gets the size of the content area of the view. *Content Area* refers to the rectangle with a location of `0,0` with a size of `ContentSize`.
+
+ The Content size tracks the size of the `Viewport` by default. If the content size is set via `SetContentSize()`, the content area is the provided size. If the content size is larger than the `Viewport`, scrolling is enabled. 
+
+## The Viewport
+
+The Viewport (`View.Viewport`) is a rectangle describing the portion of the *Content Area* that is currently visible to the user. It is a "portal" into the content. The `Viewport.Location` is relative to the top-left corner of the inner rectangle of `View.Padding`. If `Viewport.Size` is the same as `View.GetContentSize()`, `Viewport.Location` will be `0,0`. 
+
+To enable scrolling call `View.SetContentSize()` and then set `Viewport.Location` to positive values. Making `Viewport.Location` positive moves the Viewport down and to the right in the content. 
+
+The `View.ViewportSettings` property controls how the Viewport is constrained. By default, the `ViewportSettings` is set to `ViewportSettings.None`. To enable the viewport to be moved up-and-to-the-left of the content, use `ViewportSettings.AllowNegativeX` and or `ViewportSettings.AllowNegativeY`. 
+
+The default `ViewportSettings` also constrains the Viewport to the size of the content, ensuring the right-most column or bottom-most row of the content will always be visible (in v1 the equivalent concept was `ScrollBarView.AlwaysKeepContentInViewport`). To allow the Viewport to be smaller than the content, set `ViewportSettings.AllowXGreaterThanContentWidth` and/or `ViewportSettings.AllowXGreaterThanContentHeight`.
+
+## Layout
+
+Terminal.Gui provides a rich system for how views are laid out relative to each other. The position of a view is set by setting the `X` and `Y` properties, which are of time [Pos](~/api/Terminal.Gui.Pos.yml). The size is set via `Width` and `Height`, which are of type [Dim](~/api/Terminal.Gui.Dim.yml).
+
+```cs
+var label1 = new Label () { X = 1, Y = 2, Width = 3, Height = 4, Title = "Absolute")
+
+var label2 = new Label () {
+    Title = "Computed",
+    X = Pos.Right (otherView),
     Y = Pos.Center (),
     Width = Dim.Fill (),
-    Height = 1
+    Height = Dim.Percent (50)
 };
-
 ```
 
-When using *Computed Layout* the `X` and `Y` properties are of type [Pos](~/api/Terminal.Gui.Pos.yml) and the `Width` and `Height` properties are of type [Dim](~/api/Terminal.Gui.Dim.yml) both of which can be created implicitly from integer values.
+The `Frame` property is a rectangle that provides the current location and size of the view relative to the View's `Superview`'s Content area. 
 
 ## The `Pos` Type
 
-The `Pos` type on `X` and `Y` offers a few options:
-* Absolute position, by passing an integer
-* Percentage of the parent's view size - `Pos.Percent(n)`
-* Anchored from the end of the dimension - `AnchorEnd(int margin=0)`
-* Centered, using `Center()`
-* Reference the Left (X), Top (Y), Bottom, Right positions of another view
+The [Pos](~/api/Terminal.Gui.Pos.yml) is the type of `View.X` and `View.Y` and supports the following sub-types:
 
-The `Pos` values can be added or subtracted, like this:
+* Absolute position, by passing an integer - `Pos.Absolute(n)`.
+* Percentage of the parent's view size - `Pos.Percent(percent)`.
+* Anchored from the end of the dimension - `Pos.AnchorEnd()`.
+* Centered, using `Pos.Center()`.
+* The `Pos.Left(otherView)`, `Pos.Top(otherView)`, `Pos.Bottom(otherView)`, `Pos.Right(otherView)` positions of another view.
+* Aligned (left, right, center, etc...) with other views - `Pos.Justify(Justification)`.
 
-```csharp
+All `Pos` coordinates are relative to the Superview's content area.
+
+`Pos` values can be combined using addition or subtraction:
+
+```cs
 // Set the X coordinate to 10 characters left from the center
 view.X = Pos.Center () - 10;
-
 view.Y = Pos.Percent (20);
 
 anotherView.X = AnchorEnd (10);
 anotherView.Width = 9;
 
 myView.X = Pos.X (view);
-myView.Y = Pos.Bottom (anotherView);
+myView.Y = Pos.Bottom (anotherView) + 5;
 ```
-
 ## The `Dim` Type
 
-The `Dim` type is used for the `Width` and `Height` properties on the View and offers
-the following options:
+The [Dim](~/api/Terminal.Gui.Dim.yml) is the type of `View.Width` and `View.Height` and supports the following sub-types:
 
-* Absolute size, by passing an integer
-* Percentage of the parent's view size - `Dim.Percent(n)`
-* Fill to the end - `Dim.Fill ()`
-* Reference the Width or Height of another view
+* Absolute size, by passing an integer - `Dim.Absolute(n)`.
+* Percentage of the Superview's Content Area  - `Dim.Percent(percent)`.
+* Fill to the end of the Superview's Content Area - `Dim.Fill ()`.
+* Reference the Width or Height of another view - `Dim.Width (otherView)`, `Dim.Height (otherView)`.
+* An arbitrary function - `Dim.Function(fn)`
+* Automatic size based on the View's content (either Subviews or Text) - `Dim.Auto()` - See the [DimAuto Deep Dive](dimauto.md) for more information.
 
-Like, `Pos`, objects of type `Dim` can be added an subtracted, like this:
+All `Dim` dimensions are relative to the Superview's content area.
 
+Like, `Pos`, objects of type `Dim` can be combined using addition or subtraction, like this:
 
-```csharp
+```cs
 // Set the Width to be 10 characters less than filling 
 // the remaining portion of the screen
 view.Width = Dim.Fill () - 10;
 
 view.Height = Dim.Percent(20) - 1;
 
-anotherView.Height = Dim.Height (view)+1
+anotherView.Height = Dim.Height (view) + 1;

+# Migrating From v1 To v2
+
+This document provides an overview of the changes between Terminal.Gui v1 and v2. It is intended to help developers migrate their applications from v1 to v2.
+
+For detailed breaking change documentation check out this Discussion: https://github.com/gui-cs/Terminal.Gui/discussions/2448
+
+## View Constructors -> Initializers
+
+In v1, [View](~/api/Terminal.Gui.View.yml) and most sub-classes, had multiple constructors that took a variety of parameters. In v2, the constructors have been replaced with initializers. This change was made to simplify the API and make it easier to use. In addition, the v1 constructors drove a false (and needlessly complex) distinction between "Absoulte" and "Computed" layout. In v2, the layout system is much simpler and more intuitive.
+
+### How to Fix
+
+Replace the constructor calls with initializer calls.
+
+```diff
+- var myView = new View (new Rect (10, 10, 40, 10));
++ var myView = new View { X = 10, Y = 10, Width = 40, Height = 10 };
+```
+
+## TrueColor Support - 24-bit Color is the default
+
+Terminal.Gui v2 now supports 24-bit color by default. This means that the colors you use in your application will be more accurate and vibrant. If you are using custom colors in your application, you may need to update them to use the new 24-bit color format.
+
+The [Attribute](~/api/Terminal.Gui.Attribute.yml) class has been simplified. Color names now match the ANSI standard ('Brown' is now called 'Yellow')
+
+### How to Fix
+
+Static class `Attribute.Make` has been removed. Use constructor instead
+
+```diff
+- var c = Attribute.Make(Color.BrightMagenta, Color.Blue);
++ var c = new Attribute(Color.BrightMagenta, Color.Blue);
+```
+
+```diff
+- var c = Color.Brown;
++ var c = Color.Yellow;
+```
+
+## Low-Level Type Changes
+
+* `Rect` -> `Rectangle`
+* `Point` -> `Point`
+* `Size` -> `Size`
+
+### How to Fix
+
+* Replace `Rect` with `Rectangle`
+
+
+## `NStack.string` has been removed. Use `System.Rune` instead. 
+
+See [Unicode](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#unicode) for details.
+
+### How to Fix
+
+Replace `using` statements with the `System.Text` namespace
+
+```diff
+- using NStack;
++ using System.Text;
+```
+
+Anywhere you have an implicit cast from `char` to `Rune`, replace with a constructor call 
+
+```diff
+- myView.AddRune(col, row, '▄');
++ myView.AddRune(col, row, new Rune('▄'));
+```
+
+When measuring the screen space taken up by a `Rune` use `GetColumns()`
+
+```diff
+- Rune.ColumnWidth(rune);
++ rune.GetColumns();
+```
+When measuring the screen space taken up by a `string` you can use the extension method `GetColumns()`
+
+```diff 
+- myString.Sum(c=>Rune.ColumnWidth(c));
++ myString.GetColumns();
+```
+
+## `View Life Cycle Management
+
+In v1, [View](~/api/Terminal.Gui.View.yml) was derived from `Responder` which supported `IDisposable`. In v2, `Responder` has been removed and [View](~/api/Terminal.Gui.View.yml) is the base-class supporting `IDisposable`. 
+
+In v1, [Application.Init](~/api/Terminal.Gui./Terminal.Gui.Application.Init) automatically created a toplevel view and set [Applicaton.Top](~/api/Terminal.Gui.Applicaton.Top.yml). In v2, [Application.Init](~/api/Terminal.Gui.Application.Init.yml) no longer automatically creates a toplevel or sets [Applicaton.Top](~/api/Terminal.Gui.Applicaton.Top.yml); app developers must explicitly create the toplevel view and pass it to [Appliation.Run](~/api/Terminal.Gui.Appliation.Run.yml) (or use `Application.Run<myTopLevel>`). Developers are responsible for calling `Dispose` on any toplevel they create before exiting. 
+
+### How to Fix
+
+* Replace `Responder` with [View](~/api/Terminal.Gui.View.yml)
+* Update any code that assumes `Application.Init` automatically created a toplevel view and set `Applicaton.Top`.
+* Update any code that assumes `Application.Init` automatically disposed of the toplevel view when the application exited.
+
+## [Pos](~/api/Terminal.Gui.Pos.yml) and [Dim](~/api/Terminal.Gui.Dim.yml) types now adhere to standard C# idioms
+
+* In v1, the [Pos](~/api/Terminal.Gui.Pos.yml) and [Dim](~/api/Terminal.Gui.Dim.yml) types (e.g. [Pos.PosView](~/api/Terminal.Gui.Pos.PosView.yml)) were nested classes and marked [internal](~/api/Terminal.Gui.internal.yml). In v2, they are no longer nested, and have appropriate public APIs. 
+* Nullabilty is enabled.
+* Methods & properties follow standards.
+* The static method that creates a [PosAbsolute](~/api/Terminal.Gui.PosAbsolute.yml), `Pos.At`, was renamed to [Pos.Absolute](~/api/Terminal.Gui.Pos.Absolute.yml) for consistency.
+* The static method that crates as [DimAbsoulte](~/api/Terminal.Gui.DimAbsoulte.yml), `Dim.Sized`, was renamed to [Dim.Absolute](~/api/Terminal.Gui.Dim.Absolute.yml) for consistency.
+
+### How to Fix
+
+* Search and replace `Pos.Pos` -> `Pos`.
+* Search and replace `Dim.Dim` -> `Dim`.
+* Search and replace `Pos.At` -> `Pos.Absolute`
+* Search and replace `Dim.Sized` -> `Dim.Absolute`
+* Search and replace `Dim.Anchor` -> `Dim.GetAnchor`
+* Search and replace `Pos.Anchor` -> `Pos.GetAnchor`
+
+## Layout Improvements
+
+In v2, the layout system has been improved to make it easier to create complex user interfaces. If you are using custom layouts in your application, you may need to update them to use the new layout system.
+
+* The distinction between `Absoulte Layout` and `Computed Layout` has been removed, as has the `LayoutStyle` enum. v1 drew a false distinction between these styles. 
+* [View.Frame](~/api/Terminal.Gui.View.Frame.yml) now represents the position and size of the view in the superview's coordinate system. The `Frame` property is of type `Rectangle`.
+* [View.Bounds](~/api/Terminal.Gui.View.Bounds.yml) has been replaced by [View.Viewport](~/api/Terminal.Gui.View.Viewport.yml). The `Viewport` property represents the visible area of the view in its own coordinate system. The `Viewport` property is of type `Rectangle`.
+* [View.GetContentSize()](~/api/Terminal.Gui.View.GetContentSize.yml) represents the size of the view's content. This replaces `ScrollView` and `ScrollBarView` in v1. See more below.
+
+### How to Fix
+
+### `Bounds` -> `Viewport`
+
+* Remove all references ot `LayoutStyle`.
+* Rename `Bounds` to `Viewport`. The `Location` property of `Bounds` can now have non-zero values.
+* Update any code that assumed `Bounds.Location` was always `Point.Empty`.
+* Update any code that used `Bounds` to refer to the size of the view's content. Use `GetContentSize()` instead.
+* Update any code that assumed `Bounds.Size` was the same as `Frame.Size`. `Frame.Size` defines the size of the view in the superview's coordinate system, while `Viewport.Size` defines the visible area of the view in its own coordinate system.
+* Use [View.GetAdornmentsThickness](~/api/Terminal.Gui.View.GetAdornmentsThickness.yml) to get the total thickness of the view's border, margin, and padding.
+* Not assume a View can draw outside of 'Viewport'. Use the 'Margin', 'Border', and 'Padding' Adornments to do things outside of `Viewport`. View subclasses should not implement their own concept of padding or margins but leverage these `Adornments` instead. 
+* Mouse and draw events now provide coordinates relative to the `Viewport` not the `Frame`.
+
+## `View.AutoSize` has been removed. Use [Dim.Auto](~/api/Terminal.Gui.Dim.Auto.yml) for width or height instead.
+
+In v1, `View.AutoSize` was used to size a view to its `Text`. In v2, `View.AutoSize` has been removed. Use [Dim.Auto](~/api/Terminal.Gui.Dim.Auto.yml) for width or height instead.
+
+### How to Fix
+
+* Replace `View.AutoSize = true` with `View.Width = Dim.Auto` or `View.Height = Dim.Auto` as needed. See the [DimAuto Deep Dive](dimauto.md) for more information.
+
+## Adornments
+
+In v2, the `Border`, `Margin`, and `Padding` properties have been added to all views. This simplifies view development and enables a sophisticated look and feel. If you are using custom borders, margins, or padding in your application, you may need to update them to use the new properties.
+
+* `View.Border` is now of type [Adornment](~/api/Terminal.Gui.Adornment.yml). [View.BorderStyle](~/api/Terminal.Gui.View.BorderStyle.yml) is provided as a convenience property to set the border style (`myView.BorderStyle = LineStyle.Double`).
+
+### How to Fix
+
+## Built-in Scrolling
+
+In v1, scrolling was enabled by using `ScrollView` or `ScrollBarView`. In v2, the base [View](~/api/Terminal.Gui.View.yml) class supports scrolling inherently. The area of a view visible to the user at a given moment was previously a rectangle called `Bounds`. `Bounds.Location` was always `Point.Empty`. In v2 the visible area is a rectangle called `Viewport` which is a protal into the Views content, which can be bigger (or smaller) than the area visible to the user. Causing a view to scroll is as simple as changing `View.Viewport.Location`. The View's content described by [View.GetContentSize()](~/api/Terminal.Gui.View.GetContentSize.yml). See [Layout](layout.md) for details.
+
+### How to Fix
+
+* Replace `ScrollView` with [View](~/api/Terminal.Gui.View.yml) and use `Viewport` and [View.GetContentSize()](~/api/Terminal.Gui.View.GetContentSize.yml) to control scrolling.
+* Update any code that assumed `Bounds.Location` was always `Point.Empty`.
+* Update any code that used `Bounds` to refer to the size of the view's content. Use [View.GetContentSize()](~/api/Terminal.Gui.View.GetContentSize.yml) instead.
+* Update any code that assumed `Bounds.Size` was the same as `Frame.Size`. `Frame.Size` defines the size of the view in the superview's coordinate system, while `Viewport.Size` defines the visible area of the view in its own coordinate system.
+
+## Updated Keyboard API
+
+The API for handling keyboard input is significantly improved. See [Keyboard API](keyboard.md).
+
+* The [Key](~/api/Terminal.Gui.Key.yml) class replaces the `KeyEvent` struct and provides a platform-independent abstraction for common keyboard operations. It is used for processing keyboard input and raising keyboard events. This class provides a high-level abstraction with helper methods and properties for common keyboard operations. Use this class instead of the low-level [KeyCode](~/api/Terminal.Gui.KeyCode.yml) enum when possible. See [Key](~/api/Terminal.Gui.Key.yml) for more details.
+* The preferred way to enable Application-wide or View-heirarchy-dependent keystrokes is to use the [Shortcut](~/api/Terminal.Gui.Shortcut.yml) View or the built-in View's that utilize it, such as the [Bar](~/api/Terminal.Gui.Bar.yml)-based views.
+* The preferred way to handle single keystrokes is to use **Key Bindings**. Key Bindings map a key press to a [Command](~/api/Terminal.Gui.Command.yml). A view can declare which commands it supports, and provide a lambda that implements the functionality of the command, using `View.AddCommand()`. Use the [View.Keybindings](~/api/Terminal.Gui.View.Keybindings.yml) to configure the key bindings.
+* For better consistency and user experience, the default key for closing an app or `Toplevel` is now `Esc` (it was previously `Ctrl+Q`).
+
+### How to Fix
+
+* Replace `KeyEvent` with `Key`
+* Use [View.AddCommand](~/api/Terminal.Gui.View.AddCommand.yml) to define commands your view supports.
+* Use [View.Keybindings](~/api/Terminal.Gui.View.Keybindings.yml) to configure key bindings to `Command`s.
+* It should be very uncommon for v2 code to override `OnKeyPressed` etc... 
+* Anywhere `Ctrl+Q` was hard-coded as the "quit key", replace with `Application.QuitKey`.
+
+## Updated Mouse API
+
+The API for mouse input is now internally consistent and easier to use.
+
+* The [MouseEvent](~/api/Terminal.Gui.MouseEvent.yml) class replaces `MouseEventEventArgs`.
+* More granular APIs are provided to ease handling specific mouse actions. See [Mouse API](mouse.md).
+* Views can use the [View.Highlight](~/api/Terminal.Gui.View.Highlight.yml) event to have the view be visibly highlighted on various mouse events.
+* Views can set `View.WantContinousButtonPresses = true` to have their [Command.Accept](~/api/Terminal.Gui.Command.Accept.yml) command be invoked repeatedly as the user holds a mouse button down on the view.
+* Mouse and draw events now provide coordinates relative to the `Viewport` not the `Screen`.
+
+### How to Fix
+
+* Replace `MouseEventEventArgs` with `MouseEvent`
+* Use the [View.Highlight](~/api/Terminal.Gui.View.Highlight.yml) event to have the view be visibly highlighted on various mouse events.
+* Set `View.WantContinousButtonPresses = true` to have the [Command.Accept](~/api/Terminal.Gui.Command.Accept.yml) command be invoked repeatedly as the user holds a mouse button down on the view.
+* Update any code that assumed mouse events provided coordinates relative to the `Screen`.
+
+## Cursor and Focus
+
+The cursor and focus system has been redesigned in v2 to be more consistent and easier to use. If you are using custom cursor or focus logic in your application, you may need to update it to use the new system.

+* Use [Application.MostFocusedView](~/api/Terminal.Gui.Application.MostFocusedView.yml) to get the most focused view in the application.
+* Use [View.CursorPosition](~/api/Terminal.Gui.View.CursorPosition.yml) to set the cursor position in a view. Set [View.CursorPosition](~/api/Terminal.Gui.View.CursorPosition.yml) to `null` to hide the cursor.
+* Set [View.CursorVisibility](~/api/Terminal.Gui.View.CursorVisibility.yml) to the cursor style you want to use.
+* Remove any overrides of `OnEnter` and `OnLeave` that explicitly change the cursor.
+
+## Events now use `object sender, EventArgs args` signature
+
+Previously events in Terminal.Gui used a mixture of `Action` (no arguments), `Action<string>` (or other raw datatype) and `Action<EventArgs>`. Now all events use the `EventHandler<EventArgs>` [standard .net design pattern](https://learn.microsoft.com/en-us/dotnet/csharp/event-pattern#event-delegate-signatures).
+
+For example, `event Action`<long> TimeoutAdded` has become `event EventHandler<TimeoutEventArgs> TimeoutAdded`
+
+This change was made for the following reasons:
+
+- Event parameters are now individually named and documented (with xmldoc)
+- Future additions to event parameters can be made without being breaking changes (i.e. adding new properties to the EventArgs class)
+
+For example:
+
+```csharp
+
+public class TimeoutEventArgs : EventArgs {
+
+	/// <summary>
+	/// Gets the <see cref="DateTime.Ticks"/> in UTC time when the 
+	/// <see cref="Timeout"/> will next execute after.
+	/// </summary>
+	public long Ticks { get; }
+
+[...]
+}
+```
+
+## How To Fix
+If you previously had a lamda expression, you can simply add the extra arguments:
+
+```diff
+- btnLogin.Clicked += () => { /*do something*/ };
++ btnLogin.Clicked += (s,e) => { /*do something*/ };
+```
+
+If you have used a named method instead of a lamda you will need to update the signature e.g.
+
+```diff
+- private void MyButton_Clicked ()
++ private void MyButton_Clicked (object sender, EventArgs e)
+```
+
+## `ReDraw` is now `Draw`
+
+### How to Fix
+
+* Replace `ReDraw` with `Draw`
+* Mouse and draw events now provide coordinates relative to the `Viewport` not the `Frame`.
+
+## No more nested classes
+
+All public classes that were previously [nested classes](https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/nested-types) are now in the root namespace as their own classes.
+
+### How To Fix
+Replace references to to nested types with the new standalone version
+
+```diff
+- var myTab = new TabView.Tab();
++ var myTab = new Tab();
+```
+
+## View and Text Alignment Changes
+
+In v1, both `TextAlignment` and `VerticalTextAlignment` enums were used to align text in views. In v2, these enums have been replaced with the [Alignment](~/api/Terminal.Gui.Alignment.yml) enum. The [View.TextAlignment](~/api/Terminal.Gui.View.TextAlignment.yml) property controls horizontal text alignment and the [View.VerticalTextAlignment](~/api/Terminal.Gui.View.VerticalTextAlignment.yml) property controls vertical text alignment.
+
+v2 now supports [Pos.Align](~/api/Terminal.Gui.Pos.Align.yml) which enables views to be easily aligned within their Superview. 
+
+The [Aligner](~/api/Terminal.Gui.Aligner.yml) class makes it easy to align elements (text, Views, etc...) within a container. 
+
+### How to Fix
+
+* Replace `VerticalAlignment.Middle` is now [Alignment.Center](~/api/Terminal.Gui.Alignment.Center.yml). 
+
+## `StatusBar`- `StatusItem` is replaced by `Shortcut`
+
+[StatusBar](~/api/Terminal.Gui.StatusBar.yml) has been upgraded to utilize [Shortcut](~/api/Terminal.Gui.Shortcut.yml).
+
+### How to Fix
+
+```diff
+-  var statusBar = new StatusBar (
+-                                       new StatusItem []
+-                                       {
+-                                           new (
+-                                                Application.QuitKey,
+-                                                $"{Application.QuitKey} to Quit",
+-                                                () => Quit ()
+-                                               )
+-                                       }
+-                                      );
++ var statusBar = new StatusBar (new Shortcut [] { new (Application.QuitKey, "Quit", Quit) });
+```
+
+## `CheckBox` - API renamed and simplified
+
+In v1 `CheckBox` used `bool?` to represent the 3 states. To support consistent behavior for the `Accept` event, `CheckBox` was refactored to use the new `CheckState` enum instead of `bool?`.
+
+Additionally the `Toggle` event was renamed `CheckStateChanging` and made cancelable. The `Toggle` method was renamed to `AdvanceCheckState`.
+
+### How to Fix
+
+```diff
+-var cb = new CheckBox ("_Checkbox", true); {
+-				X = Pos.Right (label) + 1,
+-				Y = Pos.Top (label) + 2
+-			};
+-			cb.Toggled += (e) => {
+-			};
+-           cb.Toggle ();
++
++var cb = new CheckBox ()
++{ 
++	Title = "_Checkbox",
++	CheckState = CheckState.Checked
++}
++cb.CheckStateChanging += (s, e) =>
++{	
++	e.Cancel = preventChange;
++}
++preventChange = false;
++cb.AdvanceCheckState ();
+```

+# Mouse API
+
+## Tenets for Terminal.Gui Mouse Handling (Unless you know better ones...)
+
+Tenets higher in the list have precedence over tenets lower in the list.
+
+* **Keyboard Required; Mouse Optional** - Terminal users expect full functionality without having to pick up the mouse. At the same time they love being able to use the mouse when it makes sense to do so. We strive to ensure anything that can be done with the keyboard is also possible with the mouse. We avoid features that are only useable with the mouse.
+
+* **Be Consistent With the User's Platform** - Users get to choose the platform they run *Terminal.Gui* apps on and those apps should respond to mouse input in a way that is consistent with the platform. For example, on Windows ???
+
+## Mouse APIs
+
+At the core of *Terminal.Gui*'s mouse API is the *[MouseEvent](~/api/Terminal.Gui.MouseEvent.yml)* class. The `MouseEvent` class provides a platform-independent abstraction for common mouse events. Every mouse event can be fully described in a `MouseEvent` instance, and most of the mouse-related APIs are simply helper functions for decoding a `MouseEvent`.
+
+When the user does something with the mouse, the `ConsoleDriver` maps the platform-specific mouse event into a `MouseEvent` and calls `Application.OnMouseEvent`. Then, `Application.OnMouseEvent` determines which `View` the event should go to. The `View.OnMouseEvent` method can be overridden or the `View.MouseEvent` event can be subscribed to, to handle the low-level mouse event. If the low-level event is not handled by a view, `Appliation` will then call the appropriate high-level helper APIs. For example, if the user double-clicks the mouse, `View.OnMouseClick` will be called/`View.MouseClick` will be fired with the event arguments indicating which mouse button was double-clicked. 
+
+## Mouse Button and Movement Concepts
+
+* **Down** - Indicates the user pushed a mouse button down.
+* **Pressed** - Indicates the mouse button is down; for example if the mouse was pressed down and remains down for a period of time.
+* **Released** - Indicates the user released a mouse button.
+* **Clicked** - Indicates the user pressed then released the mouse button while over a particular View. 
+* **Moved** - Indicates the mouse moved to a new location since the last mouse event.
+
+## **[Global Mouse Handling](~/api/Terminal.Gui.Application.yml#Terminal_Gui_Application_MouseEvent)**
+
+The `Application.MouseEvent` event can be used if an application wishes to recieve all mouse events.

+# Navigation Deep Dive
+
+**Navigation** refers to the user-experience for moving Focus between views in the application view-hierarchy. It applies to the following questions:
+
+- What are the visual cues that help the user know which element of an application is receiving keyboard and mouse input (which one has focus)? 
+- How does the user change which element of an application has focus?
+- How does the user change which element of an application has focus?
+- What are the visual cues that help the user know what keystrokes will change the focus?
+- What are the visual cues that help the user know what keystrokes will cause action in elements of the application that don't currently have focus?
+- What is the order in which UI elements are traversed when using keyboard navigation?
+
+## Lexicon & Taxonomy
+
+- **Navigation** - Refers to the user-experience for moving Focus between views in the application view-hierarchy.
+- **Focus** - Indicates which view-hierarchy is receiving keyboard input. Only one view-hierarchy in an application can have focus (`top.HasFocus == true`), and there  one, and only one, View in a focused hierarchy that is the most-focused; the one receiving keyboard input. 
+- **Cursor** - A visual indicator to the user where keyboard input will have an impact. There is one Cursor per terminal session. See [Cursor](cursor.md) for a deep-dive.
+- **Tab** - Describes the `Tab` key found on all keyboards, a break in text that is wider than a space, or a UI element that is a stop-point for keyboard navigation. The use of the word "Tab" for this comes from the typewriter, and is re-enforced by the existence of a `Tab` key on all keyboards.
+- **TabStop** - A `View` that is an ultimate stop-point for keyboard navigation. In this usage, ultimate means the `View` has no focusable subviews. The `Application.NextTabStopKey` and `Application.PrevTabStopKey` are `Key.Tab` and `Key.Tab.WithShift` respectively. These keys navigate only between peer-views. 
+- **TabGroup** - A `View` that is a container for other focusable views. The `Application.NextTabGroupKey` and `Application.PrevTabGroupKey` are `Key.PageDown.WithCtrl` and `Key.PageUp.WithCtrl` respectively. These keys enable the user to use the keyboard to navigate up and down the view-hierarchy. 
+- **Enter** / **Gain** - Means a View that previously was not focused is now becoming focused. "The View is entering focus" is the same as "The View is gaining focus".
+- **Leave** / **Lose** - Means a View that previously was focused is now becoming un-focused. "The View is leaving focus" is the same as "The View is losing focus".
+
+## Tenets for Terminal.Gui UI Navigation (Unless you know better ones...)
+
+See the [Keyboard Tenets](keyboard.md) as they apply as well.
+
+Tenets higher in the list have precedence over tenets lower in the list.
+
+* **One Focus Per App** - It should not be possible to have two views be the "most focused" view in an application.
+
+* **There's Always a Way With The Keyboard** - The framework strives to ensure users' wanting to use the keyboard can't get into a situation where some element of the application is not accessible via the keyboard. For example, we have unit tests that ensure built-in Views will all have at least one navigation key that advances focus. Another example: As long as a View with a HotKey is visible and enabled, regardless of view hierarchy, if the user presses that hotkey, the action defined by the hotkey will happen (and, by default the View that defines it will be focused). 
+
+* **Flexible Overrides** - The framework makes it easy for navigation changes to be made from code and enables changing of behavior to be done in flexible ways. For example a view can be prevented from getting focus by setting `CanFocus` to `false`, overriding `OnEnter` and returning `true` to cancel, or subscribing to `Enter` and setting `Cancel` to `true`. 
+
+* **Decouple Concepts** - In v1 `CanFocus` is tightly coupled with `HasFocus`, `TabIndex`, `TabIndexes`, and `TabStop` and vice-versa. There is a bunch of "magic" logic that automatically attempts to keep these concepts aligned. This results in a bunch of poorly specified, hard to test, and fragile APIs. In v2 we strive to keep the related navigation concepts decoupled. For example, `CanFocus` and `TabStop` completely distinct. A view with `CanFocus == true` can have `TabStop == NoStop` and still be focusable with the mouse.
+
+# Design
+
+## Keyboard Navigation
+
+The majority of the Terminal.Gui Navigation system is dedicated to enabling the keyboard to be used to navigate Views. 
+
+Terminal.Gui defines these keys for keyboard navigation:
+
+- `Application.NextTabStopKey` (`Key.Tab`) - Navigates to the next subview that is a `TabStop` (see below). If there is no next, the first subview that is a `TabStop` will gain focus.
+- `Application.PrevTabStopKey` (`Key.Tab.WithShift`) - Opposite of `Application.NextTabStopKey`.
+- `Key.CursorRight` - Operates identically to `Application.NextTabStopKey`.
+- `Key.CursorDown` - Operates identically to `Application.NextTabStopKey`.
+- `Key.CursorLeft` - Operates identically to `Application.PrevTabStopKey`.
+- `Key.CursorUp` - Operates identically to `Application.PrevTabStopKey`.
+- `Application.NextTabGroupKey` (`Key.F6`) - Navigates to the next view in the view-hierarchy that is a `TabGroup` (see below). If there is no next, the first view that is a `TabGroup` will gain focus.
+- `Application.PrevTabGroupKey` (`Key.F6.WithShift`) - Opposite of `Application.NextTabGroupKey`.
+
+`F6` was chosen to match [Windows](https://learn.microsoft.com/en-us/windows/apps/design/input/keyboard-accelerators#common-keyboard-accelerators)
+
+These keys are all registered as `KeyBindingScope.Application` key bindings by `Application`. Because application-scoped key bindings have the lowest priority, Views can override the behaviors of these keys (e.g. `TextView` overrides `Key.Tab` by default, enabling the user to enter `\t` into text). The `AllViews_AtLeastOneNavKey_Leaves` unit test ensures all built-in Views have at least one of the above keys that can advance. 
+
+### `HotKey`
+
+See also [Keyboard](keyboard.md) where HotKey is covered more deeply...
+
+In v2, `HotKey`s can be used to navigate across the entire application view-hierarchy. They work independently of `Focus`. This enables a user to navigate across a complex UI of nested subviews if needed (even in overlapped scenarios). An example use-case is the `AllViewsTester` scenario.
+
+Additionally, in v2, multiple Views in an application (even within the same SuperView) can have the same HotKey. Each press of the HotKey will invoke the next HotKey across the View hierarchy (NOT IMPLEMENTED YET - And may be too complex to actually implement for v2.)
+
+## Mouse Navigation
+
+Mouse-based navigation is straightforward in comparison to keyboard: If a view is focusable and the user clicks on it, it gains focus. There are some nuances, though:
+
+- If a View is focusable, and it has focusable sub-views, what happens when a user clicks on the `Border` of the View? Which sub-view (if any) will also get focus? 
+
+- If a View is focusable, and it has focusable sub-views, what happens when a user clicks on the `ContentArea` of the View? Which sub-view (if any) will also get focus? 
+
+The answer to both questions is:
+
+If the View was previously focused, and focus left, the system keeps a record of the Subview that was previously most-focused and restores focus to that Subview (`RestoreFocus()`).
+
+If the View was not previously focused, `FindDeepestFocusableView()` is used to find the deepest focusable view and call `SetFocus()` on it.
+
+For this to work properly, there must be logic that removes the focus-cache used by `RestoreFocus()` if something changes that makes the previously-focusable view not focusable (e.g. if Visible has changed).
+
+## `Application`
+
+At the application level, navigation is encapsulated within the `ApplicationNavigation` helper class which is publicly exposed via the `Application.Navigation` property.
+
+### `Application.Navigation.GetFocused ()`
+
+Gets the most-focused View in the application. Will return `null` if there is no view with focus (an extremely rare situation). This replaces `View.MostFocused` in v1.
+
+### `Application.Navigation.FocusedChanged` and `Application.Navigation.FocusedChanging`
+
+Events raised when the most-focused View in the application is changing or has changed. `FocusedChanged` is useful for apps that want to do something with the most-focused view (e.g. see `AdornmentsEditor`). `FocusChanging` is useful apps that want to override what view can be focused across an entire app. 
+
+### `Application.Navigation.AdvanceFocus (NavigationDirection direction, TabBehavior? behavior)`
+
+Causes the focus to advance (forward or backwards) to the next View in the application view-hierarchy, using `behavior` as a filter.
+
+The implementation is simple:
+
+```cs
+return Application.GetFocused()?.AdvanceFocus (direction, behavior) ?? false;
+```
+
+This method is called from the `Command` handlers bound to the application-scoped keybindings created during `Application.Init`. It is `public` as a convenience.
+
+This method replaces about a dozen functions in v1 (scattered across `Application` and `Toplevel`).
+
+## `View`
+
+At the View-level, navigation is encapsulated within `View.Navigation.cs`.
+
+## What makes a View focusable?
+
+First, only Views that are visible and enabled can gain focus. Both `Visible` and `Enabled` must be `true` for a view to be focusable. 
+
+For visible and enabled Views, the `CanFocus` property is then used to determine whether the `View` is focusable. `CanFocus` must be `true` for a View to gain focus. However, even if `CanFocus` is `true`, other factor can prevent the view from gaining focus...
+
+A visible, enabled, and `CanFocus == true` view can be focused if the user uses the mouse to clicks on it or if code explicitly calls `View.SetFocus()`. Of course, the view itself or some other code can cancel the focus (e.g. by overriding `OnEnter`).
+
+For keyboard navigation, the `TabStop` property is a filter for which views are focusable from the current most-focused. `TabStop` has no impact on mouse navigation. `TabStop` is of type `TabBehavior`.
+
+* `null` - This View is still being initialized; acts as a signal to `set_CanFocus` to set `TabStop` to `TabBehavior.TabStop` as convince for the most common use-case. Equivalent to `TabBehavior.NoStop` when determining if a view is focusable by the keyboard or not.
+* `TabBehavior.NoStop` - Prevents the user from using keyboard navigation to cause view (and by definition it's subviews) to gain focus. Note: The view can still be focused using code or the mouse.
+* `TabBehavior.TabStop` - Indicates a View is a focusable view with no focusable subviews. `Application.Next/PrevTabStopKey` will advance ONLY through the peer-Views (`SuperView.Subviews`). 
+
+* `TabBehavior.GroupStop` - Indicates a View is a focusable container for other focusable views and enables keyboard navigation across these containers. This applies to both tiled and overlapped views. For example, `FrameView` is a simple view designed to be a visible container of other views tiled scenarios. It has `TabStop` set to `TabBehavior.GroupStop` (and `Arrangement` set to `ViewArrangement.Fixed`). Likewise, `Window` is a simple view designed to be a visible container of other views in overlapped scenarios. It has `TabStop` set to `TabBehavior.GroupStop` (and `Arrangement` set to `ViewArrangement.Movable | ViewArrangement.Resizable | ViewArrangement.Overlapped`). `Application.Next/PrevGroupStopKey` will advance across all `GroupStop` views in the application (unless blocked by a `NoStop` SuperView).
+
+## How To Tell if a View has focus? And which view is the most-focused?
+
+`View.HasFocus` indicates whether the `View` is focused or not. It is the definitive signal. If the view has no focusable Subviews then this property also indicates the view is the most-focused view in the application. 
+
+Setting this property to `true` has the same effect as calling `View.SetFocus ()`, which also means the focus may not actually change as a result.
+
+If `v.HasFocus == true` then
+
+- All views up `v`'s superview-hierarchy must be focusable.
+- All views up `v`'s superview-hierarchy will also have `HasFocus == true`.
+- The deepest-subview of `v` that is focusable will also have `HasFocus == true`
+
+In other words, `v.HasFocus == true` does not necessarily mean `v` is the most-focused view, receiving input. If it has focusable sub-views, one of those (or a further subview) will be the most-focused (`Application.Navigation.Focused`).
+
+The `private bool _hasFocus` field backs `HasFocus` and is the ultimate source of truth whether a View has focus or not.
+
+### How does a user tell?
+
+In short: `ColorScheme.Focused`.
+
+(More needed for HasFocus SuperViews. The current `ColorScheme` design is such that this is awkward. See [Issue #2381](https://github.com/gui-cs/Terminal.Gui/issues/2381#issuecomment-1890814959))
+
+## How to make a View become focused?
+
+The primary `public` method for developers to cause a view to get focus is `View.SetFocus()`. 
+
+Unlike v1, in v2, this method can return `false` if the focus change doesn't happen (e.g. because the view wasn't focusable, or the focus change was cancelled).
+
+## How to make a View become NOT focused?
+
+The typical method to make a view lose focus is to have another View gain focus. 
+
+## Determining the Most Focused SubView
+
+In v1 `View` had `MostFocused` property that traversed up the view-hierarchy returning the last view found with `HasFocus == true`. In v2, `Application.Focused` provides the same functionality with less overhead.
+
+## How Does `View.Add/Remove` Work?
+
+In v1, calling `super.Add (view)` where `view.CanFocus == true` caused all views up the hierarchy (all SuperViews) to get `CanFocus` set to `true` as well. 
+
+Also, in v1, if `view.CanFocus == true`, `Add` would automatically set `TabStop`. 
+
+In v2, developers need to explicitly set `CanFocus` for any view in the view-hierarchy where focus is desired. This simplifies the implementation significantly and removes confusing behavior. 
+
+In v2, the automatic setting of `TabStop` in `Add` is retained because it is not overly complex to do so and is a nice convenience for developers to not have to set both `Tabstop` and `CanFocus`. Note we do NOT automatically change `CanFocus` if `TabStop` is changed.
+
+## Overriding `HasFocus` changes - `OnEnter/OnLeave` and `Enter/Leave`
+
+These virtual methods and events are raised when a View's `HasFocus` property is changing. In v1 they were poorly defined and weakly implemented. For example, `OnEnter` was `public virtual OnEnter` and it raised `Enter`. This meant overrides needed to know that the base raised the event and remember to call base. Poor API design. 
+
+`FocusChangingEventArgs.Handled` in v1 was documented as
+
+```cs
+    /// <summary>
+    ///     Indicates if the current focus event has already been processed and the driver should stop notifying any other
+    ///     event subscriber. It's important to set this value to true specially when updating any View's layout from inside the
+    ///     subscriber method.
+    /// </summary>
+```
+
+This is clearly copy/paste documentation from keyboard code and describes incorrect behavior. In practice this is not what the implementation does. Instead the system never even checks the return value of `OnEnter` and `OnLeave`.
+
+Additionally, in v1 `private void SetHasFocus (bool newHasFocus, View view, bool force = false)` is confused too complex. 
+
+In v2, `SetHasFocus ()` is replaced by `private bool EnterFocus (View view)` and `private bool LeaveFocus (View view)`. These methods follow the standard virtual/event pattern:
+
+- Check pre-conditions:
+    - For `EnterFocus` - If the view is not focusable (not visible, not enabled, or `CanFocus == false`) returns `true` indicating the change was cancelled.
+    - For `EnterFocus` - If `CanFocus == true` but the `SuperView.CanFocus == false` throws an invalid operation exception.
+    - For `EnterFocus` - If `HasFocus` is already `true` throws an invalid operation exception.
+    - For `LeaveFocus` - If `HasFocus` is already `false` throws an invalid operation exception.
+- Call the `protected virtual bool OnEnter/OnLeave (View?)` method. If the return value is `true` stop and return `true`, preventing the focus change. The base implementations of these simply return `false`.
+- Otherwise, raise the cancelable event (`Enter`/`Leave`). If `args.Cancel == true` stop and return `true`, preventing the focus change. 
+- Check post-conditions: If `HasFocus` has not changed, throw an invalid operation exception.
+- Return `false` indicating the change was not cancelled (or invalid).
+
+The `Enter` and `Leave` events use `FocusChangingEventArgs` which provides both the old and new Views. `FocusChangingEventArgs.Handled` changes to `Cancel` to be more clear on intent.
+
+These could also be named `Gain/Lose`. They could also be combined into a single method/event: `HasFocusChanging`. 
+
+QUESTION: Should we retain the same names as in v1 to simplify porting? Or, given the semantics of `Handled` v. `Cancel` are reversed would it be better to rename and/or combine?
+
+## `TabIndex` and `TabIndexes`
+
+### v1 Behavior
+
+In v1, within a set of focusable subviews that are TabStops, and within a view hierarchy containing TabGroups, the default order in which views gain focus is the same as the order the related views were added to the SuperView. As `superView.Add (view)` is called, each view is added to the end of the `TabIndexes` list. 
+
+`TabIndex` allows this order to be changed without changing the order in `SubViews`. When `view.TabIndex` is set, the `TabIndexes` list is re-ordered such that `view` is placed in the list after the peer-view with `TabIndex-1` and before the peer-view with `TabIndex+1`. 
+
+QUESTION: With this design, devs are required to ensure `TabIndex` is unique. It also means that `set_TabIndex` almost always will change the passed value. E.g. this code will almost always assert:
+
+```cs
+view.TabIndex = n;
+Debug.Assert (view.TabIndex == n);
+```
+
+This is horrible API design. 
+
+### Proposed New Design
+
+In `Win32` there is no concept of tab order beyond the Z-order (the equivalent to the order superview.Add was called).
+
+In `WinForms` the `Control.TabIndex` property:
+
+> can consist of any valid integer greater than or equal to zero, lower numbers being earlier in the tab order. If more than one control on the same parent control has the same tab index, the z-order of the controls determines the order to cycle through the controls.
+
+In `WPF` the `UserControl.Tabindex` property:
+
+> When no value is specified, the default value is MaxValue. The system then attempts a tab order based on the declaration order in the XAML or child collections.
+
+Terminal.Gui v2 should adopt the `WinForms` model.
+
+# Implementation Plan
+
+A bunch of the above is the proposed design. Eventually `Toplevel` will be deleted. Before that happens, the implementation will retain dual code paths:
+
+- The old `Toplevel` and `OverlappedTop` code. Only utilized when `IsOverlappedContainer == true`
+- The new code path that treats all Views the same but relies on the appropriate combination of `TabBehavior` and `ViewArrangement` settings as well as `IRunnable`.

 # Terminal.Gui v2
 
-Check out this Discussion: https://github.com/gui-cs/Terminal.Gui/discussions/2448
-
-* *Modern Look & Feel* - Apps built with Terminal.Gui now feel modern thanks to these improvements:
-	* *TrueColor support* - 24-bit color support for Windows, Mac, and Linux. Legacy 16-color systems are still supported, automatically. See [TrueColor](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#truecolor) for details.
-	* *User Configurable Color Themes* - See [Color Themes](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#color-themes) for details.
-	* *Enhanced Unicode/Wide Character support *- Terminal.Gui now supports the full range of Unicode/wide characters. See [Unicode](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#unicode) for details.
-	* *Line Canvas* - Terminal.Gui now supports a line canvas enabling high-performance drawing of lines and shapes using box-drawing glyphs. `LineCanvas` provides *auto join*, a smart TUI drawing system that automatically selects the correct line/box drawing glyphs for intersections making drawing complex shapes easy. See [Line Canvas](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#line-canvas) for details.
-	* *Enhanced Borders and Padding* - Terminal.Gui now supports a `Border`, `Margin`, and `Padding` property on all views. This simplifies View development and enables a sophisticated look and feel. See [Padding](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#padding) for details.
-	* *Modern File Dialog* - Terminal.Gui now supports a modern file dialog that includes icons (in TUI!) for files/folders, search, and a `TreeView``. See [FileDialog](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#filedialog) for details.
-* *Configuration Manager* - Terminal.Gui now supports a configuration manager enabling library and app settings to be persisted and loaded from the file system. See [Configuration Manager](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#configuration-manager) for details.
-* *Simplified API* - The entire library has been reviewed and simplified. As a result, the API is more consistent and uses modern .NET API standards (e.g. for events). This refactoring resulted in the removal of thousands of lines of code, better unit tests, and higher performance than v1. See [Simplified API](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#simplified-api) for details.

+The entire library has been reviewed and simplified. As a result, the API is more consistent and uses modern .NET API standards (e.g. for events). This refactoring resulted in the removal of thousands of lines of code, better unit tests, and higher performance than v1. See [Simplified API](overview.md#simplified-api) for details.
+
+## `View` Improvements
+* *View Lifetime Management is Now Deterministic* - In v1 the rules ofr lifetime management of `View` objects was unclear and led to non-dterministic behavior and hard to diagnose bugs. This was particularly acute in the behavior of `Application.Run`. In v2, the rules are clear and the code and unit test infrastructure tries to enforce them. 
+  * `View` and all subclasses support `IDisposable` and must be disposed (by calling `view.Dispose ()`) by whatever code owns the instance when the instance is longer needed. 
+  * To simplify programming, any `View` added as a Subview another `View` will have it's lifecycle owned by the Superview; when a `View` is disposed, it will call `Dispose` on all the items in the `Subviews` property. Note this behavior is the same as it was in v1, just clarified.
+  * In v1, `Application.End` called `Dispose ()` on `Application.Top` (via `Runstate.Toplevel`). This was incorrect as it meant that after `Application.Run` returned, `Application.Top` had been disposed, and any code that wanted to interogate the results of `Run` by accessing `Application.Top` only worked by accident. This is because GC had not actually happened; if it had the application would have crashed. In v2 `Application.End` does NOT call `Dispose`, and it is the caller to `Application.Run` who is responsible for disposing the `Toplevel` that was either passed to `Application.Run (View)` or created by `Application.Run<T> ()`.
+	* Any code that creates a `Toplevel`, either by using `top = new()` or by calling either `top = Application.Run ()` or `top = ApplicationRun<T>()` must call `top.Dispose` when complete.
+  	*  The exception to this is if `top` is passed to `myView.Add(top)` making it a subview of `myView`. This is because the semantics of `Add` are that the `myView` takes over responsibility for the subviews lifetimes. Of course, if someone calls `myView.Remove(top)` to remove said subview, they then re-take responsbility for `top`'s lifetime and they must call `top.Dispose`.
+* New! *Adornments* -  Adornments are a special form of View that appear outside the `Viewport`: `Margin`, `Border`, and `Padding`.
+* New! *Built-in Scrolling/Virtual Content Area* - In v1, to have a view a user could scroll required either a bespoke scrolling implementation, inheriting from `ScrollView`, or managing the complexity of `ScrollBarView` directly. In v2, the base-View class supports scrolling inherently. The area of a view visible to the user at a given moment was previously a rectangle called `Bounds`. `Bounds.Location` was always `Point.Empty`. In v2 the visible area is a rectangle called `Viewport` which is a protal into the Views content, which can be bigger (or smaller) than the area visible to the user. Causing a view to scroll is as simple as changing `View.Viewport.Location`. The View's content described by `View.GetContentSize()`. See [Layout](layout.md) for details.
+* New! *`Dim.Auto`* - Automatically sizes the view to fitthe view's Text, SubViews, or ContentArea.
+* Improved! *`Pos.AnchorEnd ()`* - New to v2 is `Pos.AnchorEnd ()` (with no parameters) which allows a view to be anchored to the right or bottom of the Superview. 
+* New! *`Pos.Align ()`* - Aligns a set of views horizontally or vertically (left, rigth, center, etc...).
+* ...	
+
+## New and Improved Built-in Views
+
+* *[DatePicker](~/api/Terminal.Gui.DatePicker.yml)* - NEW! 
+* *[ScrollView](~/api/Terminal.Gui.ScrollView.yml)* - Replaced by built-in scrolling.
+* *[ScrollBar](~/api/Terminal.Gui.ScrollBar.yml)* - Replaces *ScrollBarView* with a much simpler view.
+* *[Slider](~/api/Terminal.Gui.Slider.yml)* - NEW!
+* *[Shortcut](~/api/Terminal.Gui.Shortcut.yml)* - NEW! An opinionated (visually & API) View for displaying a command, helptext, key.
+* *[Bar](~/api/Terminal.Gui.Bar.yml)* - NEW! Building-block View for containing Shortcuts. Opinionated relative to Orientation but minimially so. The basis for the new StatusBar, MenuBar, and Menu views.
+* *[StatusBar](~/api/Terminal.Gui.StatusBar.yml)* - New implementation based on `Bar`
+* *[MenuBar](~/api/Terminal.Gui.MenuBar.yml)* - COMING SOON! New implementation based on `Bar`
+* *[ContextMenu](~/api/Terminal.Gui.ContextMenu.yml)* - COMING SOON! New implementation based on `Bar`
+* *[FileDialog](~/api/Terminal.Gui.FileDialog.yml)* - The new, modern file dialog includes icons (in TUI!) for files/folders, search, and a `TreeView`. 
+
+## Configuration Manager
+
+Terminal.Gui now supports a configuration manager enabling library and app settings to be persisted and loaded from the file system. See [Configuration Manager](https://gui-cs.github.io/Terminal.GuiV2Docs/docs/overview.html#configuration-manager) for details.
+
+## Updated Keyboard API
+
+The API for handling keyboard input is significantly improved. See [Keyboard API](keyboard.md).
+
+* The `Key` class replaces the `KeyEvent` struct and provides a platform-independent abstraction for common keyboard operations. It is used for processing keyboard input and raising keyboard events. This class provides a high-level abstraction with helper methods and properties for common keyboard operations. Use this class instead of the low-level `KeyCode` enum when possible. See [Key](~/api/Terminal.Gui.Key.yml) for more details.
+* The preferred way to handle single keystrokes is to use **Key Bindings**. Key Bindings map a key press to a [Command](~/api/Terminal.Gui.Command.yml). A view can declare which commands it supports, and provide a lambda that implements the functionality of the command, using `View.AddCommand()`. Use the `View.Keybindings` to configure the key bindings.
+* For better consistency and user experience, the default key for closing an app or `Toplevel` is now `Esc` (it was previously `Ctrl+Q`).
+
+## Updated Mouse API
+
+The API for mouse input is now internally consistent and easiser to use.
+
+* The `MouseEvent` class replaces `MouseEventEventArgs`.
+* More granular APIs are provided to ease handling specific mouse actions. See [Mouse API](mouse.md).
+* Views can use the `View.Highlight` event to have the view be visibly highlighted on various mouse events.
+* Views can set `View.WantContinousButtonPresses = true` to ahve their `Command.Accept` command be invoked repeatedly as the user holds a mouse button down on the view.
