Recently, we were trying to write a table of contents for a specific section in a Latex / Beamer presentation. Being too lazy to update the frame title each time the section name might change we needed an automation to do that for us!
Luckily, the following variable does the trick: \secname gets the Section name. \subsecname gets the subsection name for those that might need it.
\begin{frame}
\frametitle{Outline for \secname}
\tableofcontents[currentsection, hideothersubsections, sectionstyle=show/show]
\end{frame}
