title: How can I map ":vsplit ." to <F7> in Vim?
body: <p>I'd like to create a mapping for <code>:vsplit .</code>.</p>
  
  <p>I tried adding this to <code>.vimrc</code>...</p>
  
  <pre><code>nmap &lt;F7&gt; verticalsplit .
  </code></pre>
  
  <p>However, when I hit <code>&lt;F7&gt;</code> it goes into insert mode and inserts "<code>calsplit .tttt</code>". (Why "tttt"?)</p>
