The KEYTAB structure is used internally to map IKBD scancodes to ASCII codes.
typedef struct {
VOIDP normal;
VOIDP shift;
VOIDP caps;
VOIDP alt;
VOIDP altshift;
VOIDP altcaps;
VOIDP altgr;
} KEYTAB;
Format
normal, shift and caps are 128 byte tables, which directly map a scancode to an ascii code.
alt,altshift,altcaps and altgr, are NULL-terminated couples of values (i.e 2 bytes). The first byte is the scancode, mapped to the second byte which is the ASCII code.
Availability
normal, shift and caps are always available.
alt,altshift and altcaps are only available on TOS>=4.x,
EmuTOS and
MiNT.
altgr is only available on Milan TOS.
