Example:

\documentclass{beamer}

\begin{document}

\lecture{lecture 1}{week 1}
\begin{frame}
\end{frame}

\begin{frame}
see Lecture \ref{week 1}
\end{frame}

\end{document}

This yields

yet it would be nice to have something like "see Lecture 'lecture 1'", so printing the title of the lecture with label "week 1".

Any ideas how to implement this? Ideally, this should be compatible with cross-referencing and \includeonlylecture as explained at [TeXSE](https://tex.stackexchange.com/questions/210287/reference-to-equation-from-other-lecture-in-class-beamer)

**Icing on the cake** would be the following: having a macro \lectureref{label}, where label is a \label{}-label on a frame within the scope of a \lecture{}-lecture.

One can add the ability to \nameref a beamer lecture with this little trick:


\documentclass{beamer}

\makeatletter
\AtBeginLecture{
\phantomsection
\protected@edef\@currentlabelname{\beamer@lecturename}
\label{\beamer@currentlecturelabel}
}
\makeatother

\begin{document}

\lecture{lecture 1}{weeka}

\begin{frame}
see Lecture \nameref{weeka}
\end{frame}

\end{document}
