Opera has had that for years, firefox/chrome still haven't picked it up? Between rel=next/prev and some simple heuristics, it is pretty effective right now.
Indeed; it’s been around for ages in Opera, and all you have to do to use it is press Space at the end of a page to go to the next one. I think they planned to use the attributes to support native swipe gestures on touch devices, but that never took off, unfortunately.
