title: Is there a way to print SEL action?
body: <p>For example, I want to trace the actions sent to my canPeformAction and they are too numerous to display at each occurrence with a "hover" in the debugger.  Therefore, I want to trace to the log and examine it after my test cycle.</p>
  
  <pre><code>- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
      NSLog(@"%s: sender=%@", __FUNCTION__, sender, action);
  }
  </code></pre>
