right, but the question was "is there a function that returns the
current state of these keys at any moment". if you don't have a
GdkEventKey or GdkEventButton handy, the answer is really "no". it
sounded as if the questioner wanted to be able to check on this from
situations where such a struct would not be available.

ps. the code to do this under Xlib is amazingly baroque. you have to
fully grok the entire keycode->keysym mapping under X, just for
starters. i've been amazed that there was no simpler way to do it.
