Hit the arrows keys on your keyboard to see the alert!

<script type="text/javascript">

$(document).keydown(function(e){

	//e.which is set by jQuery for those browsers that do not normally support e.keyCode.
	var keyCode = e.keyCode || e.which;

    if (keyCode == 38) 
	{ 
       alert( "Up arrow key hit." );
       return false;
    }

    if (keyCode == 40) 
	{ 
       alert( "Down arrow key hit." );
       return false;
    }

    if (keyCode == 37) 
	{ 
       alert( "Left arrow key hit." );
       return false;
    }
