- ; This program will let you see all the scancodes
- ; returned by the keyboard handler. Press a key
- ; and the program will show you the scancode, except
- ; for ON which exits the program. Do note that the
- ; function does not return when 2nd or alpha is
- ; pressed (they are used to change cursor). The
- ; function also supports contrast change so 2nd and
- ; up/down changes the contrast but does not return.
