title: Is there a key combination in Xcode to implement a Protocol?
body: <p>In Visual Studio if I define a class to implement an interface e.g.</p>
  
  <pre><code>class MyObject : ISerializable {}
  </code></pre>
  
  <p>I am able to right click on ISerializable, select "<em>Implement Interface</em>" from the context menu and see the appropriate methods appear in my class definition.</p>
  
  <pre><code>class MyObject : ISerializable {
      #region ISerializable Members
      public void GetObjectData(SerializationInfo info, 
                  StreamingContext context)
      {
          throw new NotImplementedException();
      }
      #endregion
  }
  </code></pre>
  
  <p>Is there anything anything like this functionality available in Xcode on the Mac? I would like to be able to automatically implement Protocols in this way. Maybe with the optional methods generated but commented out.</p>
