title: Javascript: Escape key = browser back button
body: <p>In a browser how can I make the keyboard's escape key go back in Javascript. </p>
  
  <p>For example: if you visit <a href="http://bit.ly/lgmRbW" rel="noreferrer">this page</a> and click the "Fullscreen" link I'd like to press the escape key and go back to the previous page.</p>
  
  <p>What's the Javascript to make this magic happen?</p>
