Thanks @elextr , It worked,very nice to know how to do that now! Except for the keybinding. I tried to assign ctrl+F10 when prompted for the combination, but it would only register the Left control key. So I tried editing the keybindings conf file, and entered `<Primary>F10`, restarted Geany. Doesn't do anything.
Ah, well, ctrl + apostrophe worked at the prompt. Great!
