* NOTE: Not all possible remappable symbols are remapped. There are two main
* reasons:
* a) The mapping between scancode and SYSV/386 - symboltable
* is inconsistent between different versions and has some
* BIG mistakes.
* b) In X-Windows there is a difference between numpad-keys
* and normal keys. SYSV/386 uses for both kinds of keys
* the same symbol.
*
* Thus only the alpha keypad and the function keys are translated.
* Also CapsLock, NumLock, ScrollLock, Shift, Control & Alt.
