// Notes and Caveats (from the original TCXL 6.0 TCXLCOD.H file)
//
// 1. The keycode symbols suffixed with 'G' and marked in the 'G'
// column are the "Grey" keys around the numeric keypad or in a
// separate cursor-key cluster on "enhanced" keyboards. Those
// marked in the 'N' column are on numeric keypad.
// 2. The keycodes marked in the 'E' column are only available on
// "enhanced" 101/102-key keyboards with extended keyboard BIOS
// support enabled. The extended BIOS returns keycodes containing
// 0xE0 to distinguish duplicated keys, which are marked in the
// 'T' column.
// 3. If an "enhanced" keyboard and extended BIOS is detected, the
// DEFAULT is to enable extended BIOS support and translation of
// any duplicate extended keycodes.
// 4. Keycodes are ordered by character-code, then scan-code.
// 5. Control-Break, which has an actual keycode of 0x000 is
// returned as 0xFFFF.
// 6. The ASCII control-code names are shown in square brackets.
// 7. The Key_M_??? mouse-return codes are those returned by
// _MouGet().
