You can use the jQuery scroll function .scroll() and pass it a function to be called when scrolling occurs. See here for more info.

Example:

$('#targetdiv').scroll(function(event) {
  //Stuff to do when scrolled
});

You then might be able to use the event data to see if a mouse button is pressed.

You can use the scroll event. jQuery also has a scroll convenience function.

I'm not sure if you can detect the scroll direction.

I dont think you can. But I believe you can bind something to the scroll event of the div that will trigger when the div actually has it's content's scroll position changed.
