getKey() ⇒
Returns the key code of the key pressed. Returns
0 if no key is pressed.
The prefix keys (shift ¤, second function 2,
option ¥, alpha j, and drag ‚) are not
recognized by themselves; however, they modify
the keycodes of the key that follows them. For
example: ¥ Ù ƒ Ù ƒ 2 Ù.
For a listing of key codes, see Appendix B.

If the argument is a specific mode name, returns
