title: Stopping key event bubbling in Safari 4 windows
body: <p>In Safari 4 windows, it does not seem possible to stop some key events from bubbling up to the browser in Javascript.</p>
  
  <p><a href="https://stackoverflow.com/questions/1492080/disable-f5-key-in-safari-4">This question</a> got pounced on for trying to stop <kbd>F5</kbd> (a dubious design goal), but the technical problem remains... how do you stop certain key events from bubbling up in Safari 4?  For example, </p>
  
  <p>You can stop:</p>
  
  <ul>
  <li><kbd>CTRL</kbd>+<kbd>T</kbd></li>
  <li><kbd>CTRL</kbd>+<kbd>N</kbd></li>
  </ul>
  
  <p>You cannot stop:</p>
  
  <ul>
  <li><kbd>CTRL</kbd>+<kbd>F</kbd> </li>
  <li><kbd>F5</kbd></li>
  </ul>
