window.event.keyCode how to do it on Firefox?

I'm using this code to check for keydown and display the string 'Pressed' while a key is down.

<body onKeyDown=doKey(window.event.keyCode) onKeyUp=doKey2(window.event.keyCode)>



<script>

function doKey($key) {

  document.getElementById('keydown').innerHTML='Pressed';

}



function doKey2($key) {

  document.getElementById('keydown').innerHTML='';

}

</script>



<div id=keydown></div>

The problem is that for some reason it's only working on Chrome. I think the 'window.event.keyCode' doesn't return anything. How do I make it work at least in Firefox too? Thanks

<html>

    <body onKeyDown=doKey(event) onKeyUp=doKey2(event)>



    <script>

    function doKey(e) {

        evt = e || window.event; // compliant with ie6        

        document.getElementById('keydown').innerHTML = evt.keyCode+' Pressed';

    }



    function doKey2(e) {

        document.getElementById('keydown').innerHTML='';

    }

    </script>



    <div id=keydown></div>

    </body>

</html>

If we passed event as parameter, most modern browsers will work well. I have tested with Chrome 12, Firefox 4, IE 7/8/9.
