title: Emacs global-set-key to C-TAB
body: <p>I'm trying to set a key-binding to Ctrl+TAB in Emacs.  I used the following call:</p>
  
  <pre><code>(global-set-key (read-kbd-macro "C-TAB") 'my-func)
  </code></pre>
  
  <p>However, whenever I use it, I get a</p>
  
  <pre><code>&lt;C-tab&gt; is undefined
  </code></pre>
  
  <p>error message.  Trying to set the binding to "C-tab" results in an error message.</p>
  
  <p>How can I set my binding to C-TAB?</p>
