title: Jump into #include file in XCode 3 C++ project
body: <p>If my code does either:</p>
  
  <p><code>#include "file.h"</code>
  <code>#include &lt;file.h&gt;</code></p>
  
  <p>How can I jump into those files? I'm aware of "find quickly" and the "popup of included files" dropdown '#' menu, but these both only work for local includes for me.</p>
  
  <p>I'm sure I found a way once but then forgot it when I stopped working on Mac for a while and now I cannot find it again :(</p>
