title: Set focus to one thing when clicking on another?
body: <p>This is probably very simple to do in Javascript, but I don't know how to.</p>
  
  <p>Example:</p>
  
  <pre><code>&lt;input type="textbox" id="txt"&gt;
  &lt;input type="button" id="btn"&gt;
  </code></pre>
  
  <p>Say I want to click on btn and have it set focus on txt, how would I go about doing that? Thank you!</p>
