title: How to map <C-/> to toggle comments in vim?
body: <p>I use vim under iterm2. I'm using the NERDCommenter plugin, and I'd like to use Ctrl+/ to toggle comments (Trying to switch from Idea/Eclipse to vim). This is my mapping in the .vimrc :</p>
  
  <pre><code> nmap &lt;C-/&gt; &lt;leader&gt;c&lt;Space&gt;
   vmap &lt;C-/&gt; &lt;leader&gt;c&lt;Space&gt;
  </code></pre>
  
  <p>But it doesn't seem to work. What can be the reason?</p>
