# beamer footnote not showing

I was wondering what's the appropriate way to add a footnote to a LaTeX beamer presentation, because I am trying \footnote and it's not showing the footnote. It shows the number but no footnote.

Please provide a MWE that duplicates your problem. Also include any references to your preamble and the packages you include with regard to your \footnote command. – Werner Sep 6 '11 at 2:51
More specifically, the Beamer manual says "You can use the usual \footnote command." (p. 130) That is, there is no known incompatibility between a footnote and beamer. So you will need to show your document as an example (as Werner says) in order for people to diagnose why this functionality is not working for you. – Aaron Sep 6 '11 at 3:49

Here is one way of adding a footnote to a beamer presentation. By means of a minimal working example:

\documentclass{beamer}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{hanging}% http://ctan.org/pkg/hanging
\setbeamertemplate{footnote}{%
\hangpara{2em}{1}%
\makebox[2em][l]{\insertfootnotemark}\footnotesize\insertfootnotetext\par%
}
\begin{document}
\begin{frame}
\lipsum*[1]\footnote{Here is a footnote}
\end{frame}
\end{document}


See p 131 of the beamer package documentation.

\footnote[frame] {} would be a little more easy don't you think? – user13878 Apr 24 '12 at 10:40

Turning the comment from @user13878 into an answer:

\footnote[frame]{Here is a footnote}

This has the advantage of simplicity and compatibility with \beamertemplatenavigationsymbolsempty.

-

Further tuning of the comment of @user13878, the [frame] option of \footnote can be set as default option using

\let\oldfootnote\footnote
\renewcommand\footnote[1][]{\oldfootnote[frame,#1]}


In fact I'm not so expert to write the above sentences. I could wrote them by modifying this solution of David Carlisle. Anyway, they worked perfectly with me.

This is great for LyX users, as it allows using the built-in interface for footnotes with word-processor type formatting rather than having to enter TEX code. – Andreas Dec 17 '15 at 21:33
