Macs by default use the key command "command shift 3" and "command shift 4" for screen captures, which means that trying to create a quicksave3 just takes a screenshot.
A third quicksave would be handy, but I don't know the best way to make that happen. "command shift 5" could be used, but I realise that changing the quicksave commands might make things a bit odd for PC users.
