I can't figure out what they are called: at the bottom of each post, the names of previous and next posts appear (with arrows to the left and to the right), to help the reader navigate between posts. I have two categories of posts which I have separated in the "contents." But these previous/next navigation things mix them all up. That is, if one follows them, one ends up getting posts from both categories in an illogical order. Is there a way of taming these so that they can be confined to categories?
I hope you can figure out what I am talking about, it is a bit difficult to explain.
