This paper gives the codes generated by the LK35 keyboard attached to the display (but see below). Reading input from the keyboard using a handler such as LUA. will give these codes internally. each key can either be pressed by itself or in conjunction with the shift and/or control keys. Thus each key has the four possibilities:
NB: The character code produced by hardware always has the eighth bit set, thus 15 is in fact 215 (octal), but the handler LUA. strips off this bit so the character as seen by the programmer is 15 (octal).
