Global keybindings are really messy stuff and not standardized a tiny
bit. It reminds me of problems created by ATI Catalyst Control Center -
they took ctrl+alt+c, so in some cases it was impossible to write a
diacritic (ć), because CCC always popped up instead. If I were you I
would avoid defining a global keybinding.

But anyway maybe use key_snooper in Gtk::Main [1]? I don't know if this
will work, though - I have never used it.

Many thanks for your reply. I tried key_snooper, however, it looks like just grab the key binding event before the widget handler, and if the application losts focus, it still gets nothing.
