[Tex/LaTex] Latex Beamer – Toc too long

beamertable of contents

I'm preparing for a master thesis defense… but my presentation is getting a bit lengthy…

…anyways when the ToC gets too long on the side it stretches over. See attached image. Any good advise on how to fix that?

In lack of a full example file:

It's the same issue as with a non-beamer-document:

\section{This is a really long section title -- too long for a TOC} will add exactly

This is a really long section title -- too long for a TOC

to the TOC. However, any of the structuring commands (\part, \chapter etc.) has an optional argument designed to hold the short title to appear in the TOC.

\section[My short title]{This is a really long section title -- to long for a TOC} will use the

My short title

in the TOC.
