It's not a link so it need't to add "javascript:".and for compatible with mozilla(netscape 6), u should use <tag onkeypress = "alert(event.keyCode)">if u want to use function to deal with it, follow this sample:<script type="text/javascript">
function ShowKeyCode(e)
{
  if(!e) e=window.event;  // for IE
  alert(e.keyCode);
}
</script>
...
<tag onkeypress = "ShowKeyCode()">
