Perhaps ajax.
I checked the source code and appears that at least javascript to some degree must have been used since there is no hyperlink but instead an oop reference with javascript. Then and although I haven't dug in deep enough to confirm this but it appears there is some server to client communication that updates the div fields. That's about all that I have found so far.
