I have an array of posts, which could be list of all posts, or posts
of certain user, or posts from a tag search. I present it as a
paginated list, with title and brief summary. when the user selects a
post, I show the whole thing on next page.
Right now, I just have a back link to the list, but I'd like to
implement go to next / prev post in list. This is tricky because the
list is gone, of course, and it wouldn't be easy to save it, and not
easy to calculate for each post b/c it's not just "find the next/prev
one in the posts table"
I'm using the google interface and they don't have this implemented
either. the nexy/prev actually goes to the next/prev article in the
entire group and not, for example, in the search result.
