I want to map the Ctrl+Alt+4 to take a screenshot of a selected area. Right now I can do that from a terminal using gnome-screenshot -a. I have tried putting:
Control Mod1 4 :ExecCommand gnome-screenshot -a`
in my ~/.fluxbox/keys but that does not work -- probably because of the space before -a.
Is there a way to map those key combination to take a screenshot of a selected area?
