In How to \label-\ref an un-numbered section, Nathan Grigg pointed out that one could use the \hyperref commmand to create a link to a starred section as follows
\documentclass{article}\usepackage{hyperref}\begin{document}\section*{Preface to the article}\label{s:intro}\hyperref[s:intro]{Introduction}\end{document}My question now is how to create a link to a numbered subsection of that starred section?
