Literally one of the greatest things about the Opera browser was that you could browse an entire forum or whatever (longform article etc) with the Space key, because the browser would automatically go to the `next` page on hitting the bottom of the page. They also did some cool stuff with swiping to the next page on mobile.<p>Opera seemed like the only browser vendor that truly championed next/prev.<p>I only do it now as a habit because of Opera - and, since switching to Chrome after Opera's nadir, for accessibility, regardless of whether screenreaders respect it. But I probably wouldn't know about it if not for Opera.<p>It's both wistful and aspirational to use them, because this is the way browsers were supposed to work - as was generally the case with most things Opera, of course.
