JQuery: Mouse move event?
<p>I know that I can track when the mouse is moved like this:</p>

<pre><code>$("body").mousemove( function(e){
    alert( "You moved to WIDTH " + e.pageX );
} );
</code></pre>

<p>Ok. I wanna be able to tell whether the mouse pointer was moved to left or to the right.</p>

<p>I know that to do this, I'll have to know the previous mouse position and simply compare it to the current. But how can I do this?</p>
