For some reason the keyboard shortcut for New Smart Folder doesn't work for me in Finder and I can't figure out why. I have quit every program I use that can modify shortcuts - Alfred2, BetterTouchTool, TotalFinder, and PathFinder. Still, CMD-Shift-N does absolutely nothing in Finder. Selecting from the File Menu manually works fine, but the shortcut refuses to do anything.
I've also checked in the System Prefs in case there was a rogue shortcut mapped to the same keystroke there, but there is not.
How can I figure out what is preventing this shortcut from working? I've also seen other shortcuts refuse to work for reasons unknown so I'd love to really get to the bottom of this.
