yes it is possible
window.event.keyCode take the ascii value of the key pressed when called during onkeydown, onkeypressed and onkeyup in javascript. the trick is to know the ascii code for DEL. you should be able to get it with alert().
<script>
<!--
function checkDel(){
alert(window.event.keyCode);
}
//-->
</script>
...
<body onkeyup="checkDel();">
...
</body>
to the admin, sorry but i think it'll be ok if i resolve the trouble right away 😉 this way, no need for more posts.
