title: How do I change the footer/footline of a single frame in Beamer?
body: <p>So basically I've got something like this at the top of my tex file:</p>
  
  <pre><code>\setbeamertemplate{footline}{Number \insertframenumber}
  </code></pre>
  
  <p>This applies "Number &lt;#>" to the footer/footline of all frames.  Now what I want to do is change the footline for <strong>one single frame</strong>.  Surprisingly, the following doesn't work:</p>
  
  <pre><code>\begin{frame}
      \setbeamertemplate{footline}{New template \insertframenumber}
  \end{frame}
  </code></pre>
  
  <p>How do I achieve changing the footline/footer for <strong>one single frame</strong>?</p>
