How to use reference (cross-links) by their names

There are many ways to do this, see e.g. here:
http://www.tex.ac.uk/cgi-bin/texfaq2html?label=nameref

The way that works for me is the nameref command from within hyperref package. One possible usage is:

\section*{foo}
\label{sec:foo}

...
\nameref{sec:foo}
