GTK+2.2 and Key Bindings

[Keith Maika <keithm aoeex com>]

I'm making a small app that floats on the desktop with an input box, and 
I'd like to make it possible that when you press CTRL+F12, no matter 
where you are at, it will give this window focus, highlight everything, 
and let you type.  What I can't figure out is if it's possible to make 
that kind of a keyboard shortcut using GTK+ or if I'd have to tie into 
the X windows system directly to capture the keypress or if I'd have to 
tie into the WM (in which case I may drop the idea unless there's a 
standard way to do this).

I guess what I'm looking for is the gtk equivlent of the Win32API call 
RegisterHotkey()

Thanks,
