JQuery drag&move but leave the original if CTRL key is pressed?
<p>I have the following JQuery code to drag&amp;drop to change ul item orders (#list ul). How can I make it if the CTRL key is pressed, drag&amp;move but leave the original ?</p>

<pre><code>&lt;script type="text/javascript"&gt;
$(document).ready(function(){
function slideout(){
setTimeout(function(){
$("#res").slideUp("slow", function () {
      });

}, 2000);}

    $("#res").hide();
    $(function() {
    $("#list ul").sortable({ opacity: 0.4, cursor: 'move', update: function() {

            var order = $(this).sortable("serialize") + '&amp;update=update';
            $("#hload").fadeIn('fast');
            $.post("upd.php", order, function(theResponse){
                $("#res").html(theResponse);
                $("#res").slideDown('slow');
                $("#hload").fadeOut('fast');
                slideout();

            });
        }
        });
    });

});
&lt;/script&gt;
</code></pre>

<p>Thank You.</p>
