title: Xcode "move line" keyboard shortcut
body: <p>In Xcode 4, I have been sucessfully able to add new custom keyboard shortcuts to move lines around or to duplicate a line:</p>
  
  <p><strong>/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Resources/IDETextKeyBindingSet.plist</strong></p>
  
  <pre><code>&lt;key&gt;My Custom Keys&lt;/key&gt;
  &lt;dict&gt;
      &lt;key&gt;Move Line Up&lt;/key&gt;
      &lt;string&gt;selectLine:, cut:, moveUp:, moveToBeginningOfLine:, paste:, moveUp:&lt;/string&gt;
      &lt;key&gt;Move Line Down&lt;/key&gt;
      &lt;string&gt;selectLine:, cut:, moveDown:, moveToBeginningOfLine:, paste:, moveUp:&lt;/string&gt;
      &lt;key&gt;Duplicate Line&lt;/key&gt;
      &lt;string&gt;moveToBeginningOfLine:, deleteToEndOfLine:, yank:, insertNewline:, moveToBeginningOfLine:, yank:&lt;/string&gt;
      &lt;key&gt;Delete Line&lt;/key&gt;
      &lt;string&gt;selectLine:, delete:&lt;/string&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>But the <strong>Move Line Up/Down</strong> uses copy/paste, which I would like to avoid. Anyone knows how to move lines with <em>yank</em>, just like the <strong>Duplicate Line</strong> I found there: <a href="https://stackoverflow.com/questions/10266170/xcode-4-duplicate-line/13369654#13369654">Xcode duplicate line</a></p>
