Is it possible to use jquery scrollTo together with this trick?

Short version:

Hello, with this trick I mean the method to force webkit scrollbars described  here
Basically, it's 
  1. body   {
  2. position: absolute;
  3. top: 0;
  4. left: 0;
  5. bottom: 0;
  6. right: 10px;
  7. overflow-y: scroll;
  8. overflow-x: hidden;
  9. }
and so the window itself can't be scrolled, something inside the window is scrolled.
But what? Which is the object I can use together with scrollTo to make it work that way?
I tried document.scrollTo(...), $(document).scrollTo(...), $(html).scrollTo(...) and $.scrollTo(...), but neither did work.
