title: How can I make shift+spacebar page up in Vim?
body: <p>I have an entry in my .vimrc which makes it page down the viewport when I hit the spacebar. It looks like this:</p>
  
  <pre><code>map &lt;Space&gt; &lt;PageDown&gt;
  </code></pre>
  
  <p>I want to create another key mapping which pages the viewport up when holding shift and hitting the spacebar. I have tried the following entries:</p>
  
  <pre><code>map &lt;Shift&gt;&lt;Space&gt; &lt;PageUp&gt;
  map &lt;S-Space&gt; &lt;PageUp&gt;
  </code></pre>
  
  <p>Neither work. Anybody know how to achieve this functionality?</p>
