You have to use Xlib, the API call is called XGrabKey().  For GNOME
we've been trying to move all usage of this API into the window
manager, so that collisions can be handled more gracefully, etc.  But
it's generally fine to use it directly (if someone else has already
grabbed your key, then the XGrabKey() will simply fail - you may need
to gdk_error_trap_push() around the XGrabKey() to handle that).
