Stores the scan code of the key being pressed. This is set by KbdScan and read by GetCSC. It is only valid when the flag kbdSCR,(iy+kbdFlags) is set.
GetCSC can also process diagonal arrow key presses; set bit 0 of mouseFlag1 to enable this behavior, though you shouldn't return to the OS with it set. Here are the equates:
skDownLeft EQU 252 skDownRight EQU 250 skUpLeft EQU 245 skUpRight EQU 243
