A keymap structure contains pointers to arrays which determine the
translation from raw key codes to ANSI characters.

    struct KeyMap
        {
        UBYTE *km_LoKeyMapTypes;
        ULONG *km_LoKeyMap;
        UBYTE *km_LoCapsable;
        UBYTE *km_LoRepeatable;
        UBYTE *km_HiKeyMapTypes;
        ULONG *km_HiKeyMap;
        UBYTE *km_HiCapsable;
        UBYTE *km_HiRepeatable;
        };
