They're using XGrabKey(), typically on the root window. It probably
doesn't really have the semantics you want; you have to use keycodes
not keysyms, you have to specifically select all keys you're
interested in, and only one app at a time (including the window
manager as an app) can grab a given keycode/modifier combo. Check out
the XGrabKey man page.

Hmm, it doesn't cover this issue though. ;-)
