How do I simulate a scrollbar click with jQuery? So, if a user clicks on a div that says "scroll down," it'll be the exact same behavior as if he/she clicked on the down arrow of the browser's scrollbar. Using the current browser's behavior would be optimal, vs. doing something like `$.browser.scrolldown(200,'fast')`. 

Something like `$.browser.triggerDownArrowOnScrollBar()` would be sweet!
