there's probably already a question on this, but i couldn't find it.
i've been out for a few days, and would like to review what has happened while i was away. i know the number of the last question from just before i was away, and i can get to that. but i don't know how to get to that point and then proceed "upward" in the archive, so that i don't miss anything (except by inattention).
for that matter, it would be useful to learn how to invert the order of the questions, so (on request), i can look at a list with oldest first, and then skip down to a specified point. i'm sure i'm missing something obvious here ... (and, obviously, i'd like to be able to shift back to "newest first" once i get caught up.)
