As every key on keyboard had an Unicode.Some times it help when we run around java-script.
Code
<html>
<head>
<script type="text/javascript">
function whichButton(event) {
alert(event.keyCode)
}
</script>
</head>
<body onkeyup="whichButton(event)">
<p><b>Note:</b> Make sure the right frame has focus when trying this example!</p>
<p>Press a key on your keyboard. An alert box will alert the unicode of the key
pressed.</p>
</body>
</html>
<head>
<script type="text/javascript">
function whichButton(event) {
alert(event.keyCode)
}
</script>
</head>
<body onkeyup="whichButton(event)">
<p><b>Note:</b> Make sure the right frame has focus when trying this example!</p>
<p>Press a key on your keyboard. An alert box will alert the unicode of the key
pressed.</p>
</body>
</html>
