I used to use Super+C to take a screenshot with Shutter. After upgrading to Ubuntu 13.04, I have found the Super+C shortcut to be mapped to a "Search Photos" lens. I tried going through Compiz (and Google), but I haven't found a solution yet. Is there anyway to remove this shortcut? I've tried setting it in Shutter, but it won't override Unity.
I managed to solve my problem by combining two solutions I found online
Steps to Solve:
Note: shutter -s is to take a selection screen grab, you may want another option, check shutter help to determine what flag you want.
