After the first execution of the application, you can find default.csx in the directory %APPDATA%\Crevice4. It's the userscript file. Please open it with a text editor and take a look through it.
After several using declaring lines, you can see Browser definition as following (but here, a little bit shortened):
var Browser = When(ctx =>
{
return ctx.ForegroundWindow.ModuleName == "chrome.exe" ||
ctx.ForegroundWindow.ModuleName == "firefox.exe" ||
ctx.ForegroundWindow.ModuleName == "iexplore.exe");
});When the ModuleName of ForegroundWindow is one of follows, chrome.exe, firefox.exe, or iexplore.exe, then When returns true; this is the declaration of initialization of a context which specialized to Browser.
After that, the declaration of gestures follows. Let's see the first one:
Browser.
On(Keys.RButton).
On(Keys.WheelUp).
Do(ctx =>
{
SendInput.Multiple().
ExtendedKeyDown(Keys.ControlKey).
ExtendedKeyDown(Keys.ShiftKey).
ExtendedKeyDown(Keys.Tab).
ExtendedKeyUp(Keys.Tab).
ExtendedKeyUp(Keys.ShiftKey).
ExtendedKeyUp(Keys.ControlKey).
Send(); // Previous tab
});This is a mouse gesture definition; when you press and hold Keys.RButton, and then if you Keys.WheelUp it, the actions declared in Do will be executed.
As long as Crevice4 is executing, you can edit userscript file at any time. Of cause it's ok even if while you are reading the following sections. Crevice4 supports hotloading feature. Whenever Crevice4 detects an update of the userscript file, it will be compiled and evaluated immediately, then it will be loaded if the compilation is successful.

You can do anything you want by writing your own script in it, or else by just copying codes from Stack Overflow. See Overview of C# Scripting for more details.
