Onkeydown() does not work for delete and backspace in IE

Question

Does anyone know why the onkeydown() event does not work for delete and backspace key in IE? It works fine for number and character keys.

Are you sure? .. the following sees delete and backspace fine on IE:

<html>
<head>
<script type="text/javascript">
function keypress(e)
{
    var keycode;
    if (window.event) // IE
    {
        keycode = e.keyCode;
    }
    else if (e.which) // Netscape/FF/Op
    {
        keycode = e.which;
    }
    alert(keycode);
}
</script>
</head>
<body>
<form>
    <input type="text" onkeydown="return keypress(event)" />
</form>
</body>
</html>
