In Beamer, I would like to use the long, full section titles in the table of contents, but shortened titles in the headline at the top of the screen (e.g., provided by the CambridgeUS theme). The section titles are defined as follows:
\section[short title]{long title}
I tried the suggestion at https://tex.stackexchange.com/a/6866/9789 but it does not work for me. I wonder if it is because I am in Beamer.
