Here's some code I found today while poking around the net. Embed this in a web page, and a user can simply double-click anywhere on the page to automatically move back to the beginning of the page. Pretty cool idea. Here's the code:

<script language="JavaScript1.2" type="text/javascript">
<!--
function dblclick() 
{ 
  window.scrollTo(0,0) 
}
if (document.layers) 
{ 
  document.captureEvents(ONDBLCLICK); 
}
document.ondblclick=dblclick; 
-->
</script>
