Found undocumented features

[mdziczkowski]

I wanted to report finding an undocumented features (key combinations) in cmatrix, with I list bellow.

• Shift + L : displays message: "Computer Locked" and there seem to be no working combination to unlock it.

It also disables possibility to disable cmatrix from itself

• numbers from 0 to 9 control the speed of the Matrix
• some keys change the matrix into different output

Tested on:

• Devuan 5.0 (Debian based Linux) in the "minimal live" version

I've had a new manual page written fixing this since last March: #186

Hey. I don't see any mention releated to the "screen locked" issue part. Could You please add also either a section in readme or separate file containing copy of the man content?
