Special Key:
|
|
|
|
The strategy here is similar to the one used by toolkits,
|
|
which consists in leaving the 24 bits unicode range for printable
|
|
characters, and use the upper 8 bits for special keys and
|
|
modifiers. This way everything (char/keycode) can fit nicely in one 32 bits unsigned integer.
