I have this extra windows key on my keyboard, and I thought of making it control rhythmbox or something else like that. Is it possible to set "Super_L + z/x/c/v/b" to do something? If it is, then I'd like to know how. I guess it involves tweaking some x.org files.
by the way: why gnome's hotkey editor doesn't take "Super_L + something" commands? it works only with Ctrl and Alt
