title: How do I make an Xcode 4 behavior work?
body: <p>So I have a custom behavior called "Test", and it's set to ⌘-shift-pgdn. It's supposed to just play the Submarine sound. But when I hit that shortcut, it just plays the usual error sound.</p>
  
  <p>This is a test case for trying to get the Unlock behavior to run a Perforce script to unlock files.</p>
