How to invoke javascript event onKeyDown

I need to invoke javascript event onKeyDown, which should get invoked when we press any key from anywhere of the page. currently I am callin like this:

Expand|Select|Wrap|Line Numbers

 <head>

<script type="text/javascript">

//document.onKeyDown=isBack(event);

function isBack(event)

{

    alert('hit a key');

}

</script>

</head>
 
<body onKeyDown="isBack(event);">
 
<input type="text" id="myid">

</body>

Is ther any way to invoke it, other than from body. Like the line (//document.onKeyDown=isBack(event);) . will it work?

that line will definitely not work (at least not as intended)

you can attach the handler to any element/object you like, but to work global you need it to attach to window or body at least.
