Is it possible to specify page numbers that are words, e.g. “Title”?

Question

I suppose this might also go on SuperUser, but I'm only interested in it insofar as implementing it in LaTeX, so I'll ask here.

I feel certain that I've seen PDF's where the actual PDF page number of (for example) the title page is not 1 or i, or any of the standard choices I know are possible in LaTeX, but rather the word "Title", like this:

(the numbering would then continue as usual, with the second page in the document being indicated as "1" in the white box, etc.)

This is only a mock-up, because unfortunately I can't find any examples of PDFs that are like this (perhaps I've only imagined it?) but hopefully I have specified the idea well enough, and I'd like to know if it's possible to do in LaTeX.

Answer 1

Digging into hyperref source code, I discovered a macro of promising name: \thispdfpagelabel. I tried it with the following MWE:

\documentclass{article}
\usepackage{hyperref}
\usepackage{lipsum}
\begin{document}
\thispdfpagelabel{Test}
\lipsum
\newpage
\lipsum
\end{document}

Bingo! The resulting pdf has the pages numbered from 1 to 4, as usual, but Adobe Reader showed this in the status bar:
