# How to display a visual marker on the last overlay

Is it possible to display a visual "marker" on the last overlay of every frame? I want to know when an overlay "ends" before I go to the next frame.

If I understand you correctly you could end each frame with

\only<.>{STOP here}

or some other marker as in the following where the . denotes the current value of the overlay counter at the end of the frame.

\documentclass[10pt,xcolor=dvipsnames]{beamer}

\begin{document}

\begin{frame}
\begin{itemize}
\item<+-> one
\item<+-> two
\item<+-> three
\end{itemize}

\only<.>{STOP here}
\end{frame}
\begin{frame}
\begin{itemize}
\item<+-> one one
\item<+-> two two
\item<+-> three three
\end{itemize}

\only<.>{STOP here}
\end{frame}

\end{document}
\end{document}

Thank you, that works great. Is there a way to put this on every frame automatically? – Sebastian Nov 26 '12 at 8:08
you can probably go in the preamble \let\oldendframe\endframe \def\endframe{\only<.>{.....}\oldendframe – David Carlisle Nov 26 '12 at 9:35
