* http://hitmen.c02.at/files/yagcd/yagcd/chap9.html#sec9.3.2
*
* But the table appears to have been built using a PC keyboard
* converted (Tototek).
*
* I was working with an ASCII keyboard so I made a few adjustments
* to reflect the /real/ key functions. For instance:
*
* LWIN, RWIN and MENU are in fact the Henkan, muhenkan and katakana/hiragana keys.
* They are equivalemnt to the HID keys International 4, International 5 and International 2.
* The - key (code 0x3F) is also HID international 1.
* The PrntScrn key (code 0x36) is in fact the Yen key (International 3).
* The bracket/brace [{ and }] keys are at different places on this Japanese keyboard,
* but following standard PC practice, some keycodes are named after the US usage. Hence,
* the aforementioned keys are the 2 keys right of P, even if they are not labeled.
