That assumes that the visual reordering is completely random. But usually it's not, usually you are using reordering for, e.g. shifting the entire navigation section to the left or above the main content. So the ZoomText user following source order will be pulled into the main content area, skipping over the navigation sections, and then jump back up to the navigation sections--but that's the *intention*. ~fantasai
