I have shutter 0.90 on my Ubuntu 12.04 machine (installed via PPA). I would like to use it as my default screenshot tool with the Print shortcut key. But I can't find the option in Shutter. It should be in Preferences -> Keyboard, but I don't see the Keyboard option there. I also tried to make a shortcut in Ubuntu with
shutter -f. It doesn't work too.
What can I do to use shutter when I press the Print key?
