I was thinking about this recently as I added it to a site. The use case is slightly different because the site in question was more data-driven than a blog. One example is viewing an individual item and being able to navigate to the next item in alphabetical order. This uses link elements with the appropriate rel values. The problem of losing context can be mitigated by having the page return to the previous location on back, something which browsers kinda already do, just not very well. Alternatively, I assume you'd prefer some kind of modifier? This has problems of its own — e.g. shortcut clashes. YouTube uses comma and full stop as frame next/previous shortcuts — maybe we should standardise on those?
