title: Moving a DIV by scrolling
body: <p>I'm creating a jQuery scrollbar which scrolls the content in a &lt;div&gt;. It's something like <a href="http://jscrollpane.kelvinluck.com/" rel="nofollow">jQuery ScrollPane</a>. </p>
  
  <p>I've come to the point where I need to move the scroll button. My question is: what is the best way to do it without any UI plugin? So when the user clicks on the scroll button it can be moved vertically in its parent container with a mousedown event. How could I do that? </p>
