[OT] "Enter" key listener for form submittal

I found this JavaScript, which is supposed to listen for the "Enter" key 
on any browser (and submit the form on keypress). However, it doesn't 
seem to be working in IE:

<script language="JavaScript">
  if (document.layers) document.captureEvents(Event.KEYDOWN);
  document.onkeydown = 
    function (evt) {
      var keyCode = evt ? (evt.which ? evt.which : evt.keyCode) : evt.keyCode;
      if (keyCode == 13) {
        document.forms[0].submit();
      }
    }
</script>


Does anyone have an "Enter" key listener that has been shown to work in 
all browsers, or know what is wrong with this one?

Thanks,
Erik

And, now I will repost the code which was omitted in a reply:

Perhaps.  I just glanced at the thread, so I have a cursory 
understanding of the problem.

Thanks, I will try that.

Hmm, would it not fail also on Mozilla if that were true?

Thanks,

Consider returning false in order to halt the normal event propagation.  
It may be that you are triggering the right form, but the "enter" event 
is being passed on and submitting the cancel button.

Also, does document.forms[0].submit() trigger the submit with a submit 
value of cancel?  Does that make since?
