-Notice that I updated the matrix above with the following new info:
-l1:b1 is LOCK: you press it with CTRL to switch to Caps, you press it again to switch back
- (you can also use it with ALT)
-l3:b7 is ESC: you use it to exit from nested programs (e.g. if you start to write a program in BASIC,
- then start EXDOS, you can use ESC to go back to BASIC without losing the program you were writing)
-
-According to pictures and manuals, there seem to be no more keys connected, so I label the remaining N/C
-as IPT_UNUSED.
-
-Small note about natural keyboard support: currently
-- "Lock" is mapped to 'F9' (it acts like a CAPSLOCK, but no IPT_TOGGLE)
-- "Stop" is mapped to 'F10'
-- "Hold" is mapped to 'F11'
