Beamer allowframebreaks default option

Question

How do I tell beamer that I want allowframebreaks allowed by default?

Something like noitemsep for itemize: \setlist[itemize]{noitemsep}

So that I don't have to do:

\begin{frame}[allowframebreaks]
    something
\end{frame}

but just:

\begin{frame}
    something
\end{frame}

Answer 1

Since everyone is telling you not to do it, here;s one way of doing it:-)

\documentclass{beamer}

\let\oldframe\frame
\renewcommand\frame[1][allowframebreaks]{\oldframe[#1]}

\begin{document}

\begin{frame}
\begin{enumerate}
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\item    something \item    something \item    something
\end{enumerate}
\end{frame}

\end{document}

Answer 2

This doesn't answer your question, but rather details some reasons why you might not want to do that.

Presentations are not like regular documents. When constructing a presentation, every frame needs to be carefully constructed, and allowing automatic frame breaks somewhat implies that you might have copy & pasted from another document- the audience will pick up on this.

A few of guidelines that I like to adhere to:

• no more than 10 words per frame
• use (tikz/PSTricks) pictures and images wherever possible
• schedule about 1 frame per 3-5 minutes (the longer the better)- your slides need to support your talk, not the other way round

Any time that I have broken these rules, I have found that the audience is lost- do they listen to me, or do they try and read the slides?
