title: vimrc key remap seems to not work, but works in :Ex mode
body: <p>In my vimrc, I have the following:</p>
  
  <pre><code>imap &lt;S-Tab&gt; &lt;Esc&gt;&lt;&lt;i 
  </code></pre>
  
  <p>This will unindent by 1 tabs-length Shift+Tab in insert mode. Shift-Tab acts as if it is just a Tab when I have this in my vimrc though. However, if I run the following in :Ex mode:</p>
  
  <pre><code>:imap &lt;S-Tab&gt; &lt;Esc&gt;&lt;&lt;i 
  </code></pre>
  
  <p>The remapping works properly. Does anyone know what might be causing the problem? There is no other remapping of  in the vimrc. I ran  </p>
  
  <pre><code>strace -o vim_strace vim
  </code></pre>
  
  <p>to verify that the correct vimrc is being sourced and no other strange vimrc's are being sourced.</p>
  
  <p>Interestingly, I have the same exact vimrc on my local machine, and it works properly. That is, this problem is only occurring on a remote machine I am ssh'd into. </p>
  
  <p>Does anyone have any ideas that might help solve this annoying problem?</p>
