Check whether shortcut key exists/don't allow shortcut key to mutliple actions Is there an easy way to check whether a shortcut key exists already? I wanted to assign ctrl+s as "mark seam" but immediately realized that that was already the save shortcut. I'd like to be able to check whether there would be a double assignment, and if possible, not allow them.
