I generated HTML for the gdb manual using GNU Texinfo 5.0, and looked at the output.
I see this in one page: <link href="Concept-Index.html#Concept-Index" rel="previous" title="Concept Index"> >From http://www.w3.org/TR/html401/types.html#h-6.12: Prev Refers to the previous document in an ordered series of documents. Some user agents also support the synonym "Previous". I think this means that "prev" is the preferred form. Tom
