Keyboard
The keyboard is really good.
Attention: The backspace is called ‘roubout’ and you can use it with SHIFT! on the right side on top (same place like backspace)
There are three modes:
Default Inser-Line (L)
Commands (K) - Commands : Shift-Function > The command
Graphics (G) - Create the char with graphics (First Shift Graphics > Shift Key)
The whole system is a token coding thing.

You can also write LET a=10 and than work with then in the shell.
