Can't remove keyboard shortcut for vertex paint I accidentally set a shortcut to vertex paint on left mouse button but not through user preferences and (after looking at countless answers here) never found a solution that works. I've been through user settings for what seems like hundreds of times now, and still can't get the problem fixed. Would it be worth reinstalling blender? I'm new, so I haven't made much progress yet.

I'm running Blender v2.79
Under "File" choose "Load Factory Settings".
