Capture Shift, Alt and Ctrl Keys using jQuery

A user mailed me a question:

I have a Form. If a user clicks on a Button control or clicks anywhere in the form holding the Shift, Alt or Ctrl Keys, I want to capture these keys and take a different action.

Here’s how to achieve this simple task:

<html xmlns="http://www.w3.org/1999/xhtml">
<
head>
<
title>Capture Shift, Alt and Ctrl Keys</title>
<
script src="http://code.jquery.com/jquery-latest.js"
type="text/javascript"></script>
<
script type="text/javascript">
$(document).click(function(e) {
if (e.shiftKey) {
alert("Shift pressed");
}
else if (e.ctrlKey) {
alert("Ctrl Pressed");
}
else if (e.altKey) {
alert("Alt Pressed");
}
});
</script>
</
head>
<
body>

</
body>
</
html>
