keycodes are 32-bit integers.
|
|
|
|
the low byte indicates the key itself. for printable characters (and keys with
|
|
reasonable translations to ascii control codes), this is the ascii code. for
|
|
other ones, something in the range of 0x80 to 0xef is used, seen in table 1.
|
|
|
|
the top 24 bits indicate several flags. these are seen in table 2, where bit 0
|
|
is the lowest bit of the second lowest byte of the keycode, and bit 23 is the
|
|
highest bit of the highest byte of the keycode.
