title: What keys do you map <left>, <down>, <up>, <right> commands in VIM insert mode?
body: <p>In Vim it is nice to use hjkl in normal mode and would be great to continue to use them in insert mode. I tried to map them to Ctrl-h, Ctrl-j, Ctrl-k, Ctrl-l:</p>
  
  <pre><code> imap &lt;C-h&gt; &lt;left&gt;
   imap &lt;C-j&gt; &lt;down&gt;
   imap &lt;C-k&gt; &lt;up&gt;
   imap &lt;C-l&gt; &lt;right&gt;
  </code></pre>
  
  <p>but it is not convenient especially because it masks Ctrl-H and backspace stops responding.
  Have you been able somehow to use HJKL keys for movements in insert mode?</p>
