title: Map shift-tab in vim to inverse tab in Vim
body: <p>I've done some searching and found a wealth of information on binding keys in vim, but I can't find out, for sure, how to map shift-tab. Or what command I need to map it to for it to "tab backwards". </p>
  
  <p>This is what I have at the moment:</p>
  
  <pre><code>map &lt;S-tab&gt; &lt;S-,&gt;&lt;S-,&gt;
  </code></pre>
  
  <p>Possibly Relevant Information:
  I'm running Debian with Terminal 2.22.3. with VIM - Vi IMproved 7.1 </p>
