- 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.
