*
* keyboard sends 3 types of presses/releases
* - 3 byte, 1 for make code and 2 for break code. used by wasd and 123 etc
* - 5 byte, 2 for make code and 3 for break code. used by alt_gr etc
* - 10 byte, 4 for make code and 6 for break code. used by printscreen etc
*
* 1 byte make codes are self explanatory. 2 byte make codes are prefixed with
* 0xE0 byte. later called "special". 4 byte make codes are prefixed with
* special-leftshift-special (0xE0 0x12 0xE0) later called "extraspecial"
*
* following block contains "data" codes and their respective keys. please
* note that all make and break codes are constructed from "data" codes by
