An X keyCode must be in the range XkbMinLegalKeyCode (8) to
|
|
XkbMaxLegalKeyCode(255).
|
|
|
|
The keyCodes we get from the kernel range from 0 to 127, so we need to
|
|
offset the range before passing the keyCode to X.
|
|
|
|
An X KeySym is an extended ascii code that is device independent.
|
|
|
|
The modifier map is accessed by the keyCode, but the normal map is
|
|
accessed by keyCode - MIN_KEYCODE. Sigh.
