A decade ago I would navigate web pages quicker than now. I was using Opera, which had keys for navigating from hyperlink to hyperlink (spatially, using shift+arrow keys). It also keys for navigating to the logical previous and next page--that is, not navigating history, but following "link rel=prev" and "link rel=next" links. Unfortunately, the web evolved to make this harder. Everything is a hyperlink and no one uses link rel tags anymore.
