No, I don't. I gave up on understanding X keyboard handling. For the purpose of writing my app, it was enough to completely bypass X and read the keyboard stream directly. X has a very complicated while simultaneously very limited (ie. stupid) keyboard controls. It does not make the difference between left ctrl and right ctrl, for example (if the keyboard happens to have both). Same for shift keys. While it is enough for a typical mouse-oriented user, it fails to support anything more advanced in terms of keyboard. :-) Marko Marko Vojinovic Institute of Physics University of Belgrade ====================== e-mail: vmarko@xxxxxxxxxxxx
