title: Xcode 4 - changing a shortcut
body: <p>First I would like to say that I hate Xcode 4 with passion. It is obtrusive and not friendly.</p>
  
  <p>Said that, after upgrading to the new release of 4.2, one of my shortcuts stopped working and it is refusing to let me change it again.</p>
  
  <p>The shortcut was ⌥ ⌘ ⬆</p>
  
  <p>Every time I pressed this, a new window opened (if not opened yet), showing me the counter part file (.m or .h). Now, this is disabled.</p>
  
  <p>Now, there are only 3 options on the key bindings window, all assigned to other shortcuts and none does what I want. The closer is the second one: Jump to Next Counterpart (option) but this splits the window and opens the counterpart on the right half of the window and the shortcut cannot be changed (it is grayed out and locked).</p>
  
  <p>How do I solve that?  </p>
  
  <p>This is the screenshot of the bindings panel filtering for "jump"</p>
