I did something like this. But does not solve my issue. Gives "JavaScript" error:
<html>
<head>
<script language="javascript">
function func(e)
{
var unicode = e.keyCode ? e.keyCode : e.charCode;
var evtobj=window.event ? event : e;
if (evtobj.shiftKey && unicode == 9)
{
document.form1..text1.focus();
}
}
</script>
<body>
<form name="form1">
<input type="text" name="text1" onkeyup="func(event);" />
<input type="text" name="text2" onkeyup="func(event);" />
<input type="text" name="text3" onkeyup="func(event);" />
</form>
</body>
</html>
 Thanks
