title: Vim: Increase document traversal speed
body: <p>I sometimes find document traversal to be too slow in Vim when using <code>h, j, k, l</code>.
  Is there a way to temporally increase the number of lines / characters that these keys move the cursor? (I.e. instead of moving <code>1j</code>, pressing <code>j</code> will move <code>3j</code>)</p>
  
  <p>Edit:
  Solution:</p>
  
  <pre><code>:map &lt;F8&gt; :noremap j 3j &lt;CR&gt;
  :map &lt;S-F8&gt; :noremap j j &lt;CR&gt;
  </code></pre>
  
  <p>I wanted something like this so that I can easily browse longer bodies of code that am not necessarily familiar it. This approach allows me to easily toggle between "browsing" mode and "coding" mode.</p>
