Without the \pause
command, "On the first or third slide" has no specification for when to appear, which means it always appears. With the \pause
command, it uncovers the list items one at a time until they are all uncovered, and then pauses again, which is why you have the repeat slide (since nothing changes between uncovering the last item and pausing).
The solution is to specify when you want the items after the list to appear. One method of accomplishing this is to surround it with an \uncover
command:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}[<+->]
\item On the first slide
\end{itemize}
\uncover<+->{
On the second slide
}
\end{frame}
\end{document}
Edit
In response to your edit, here's another way to solve your problem. You are using \pause
in combination with the list option [<+->]
, which adds its own pauses and so results in double pauses sometimes. If you really prefer to not give up \pause
, then you can fix your example's behaviour by using it exclusively:
\documentclass{beamer}
\begin{document}
\begin{frame}
On the first slide
\pause
\begin{itemize}
\item On the second slide.
\pause On the third slide
\pause\item On the fourth slide
\end{itemize}
\end{frame}
\end{document}
This also works in your first example:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item On the first slide
\pause\item On the second slide
\end{itemize}
\pause On the third slide
\end{frame}
\end{document}
The potential down side of this approach is that \pause
stops everything after it on the current frame from appearing until the pause has passed, even if you specify that it should appear earlier. For example,
\documentclass{beamer}
\begin{document}
\begin{frame}
Here are important points:
\begin{itemize}
\item Point on Slide 1
\pause\item Point on Slide 2
\pause\item Point on Slide 3
\end{itemize}
\uncover<1-3>{
I want to emphasize this on every slide:\\ Always remember these points!\\ (But it only appears on the third slide)
}
\end{frame}
\end{document}
On the other hand, with less code you can achieve this effect simply:
\documentclass{beamer}
\begin{document}
\begin{frame}
Here are important points:
\begin{itemize}[<+->]
\item Point on Slide 1
\item Point on Slide 2
\item Point on Slide 3
\end{itemize}
Always remember these points!
\end{frame}
\end{document}
\makeatletter
\apptocmd{\beamer@@frametitle}{\only<1>{\bookmark[page=\the\c@page,level=3]{#1}}}%
{\message{** patching of \string\beamer@@frametitle succeeded **}}%
{\message{** patching of \string\beamer@@frametitle failed **}}%
\makeatother
adds the bookmark just for the first slide in each frame (or at least it seems to work on your MWE)
Best Answer
I guess there are at least three alternatives for your problem, the four slides in the following example all do the same:
<3->
meaning all starting from the third onebeamerpause
(=1 at beginning of frame) by one at each encounterEdit 1: You can also set the behaviour from the fourth example as general. All frames following
\beamerdefaultoverlayspecification{<+->}
will set pauses for everyactionenv
environment and every\item
. To be in effect globally, you need to set this outside of a frame, e.g. as the first line after\begin{document}
, before the first frame.
