# How do I change footnote in Beamer?

I would like to change footnote sign letter to numbers in my Beamer presentation. How can I achive this?

I cannot test it now, but would \def\thefootnote{\arabic{footnote}} placed just after \begin{document} help? (There was a mistake, I edited it now!) – yo' Aug 26 '12 at 18:41
Can you post a minimal example that shows the problem. The default numbering for footnotes in Beamer is numeric, not alphabetic. – Alan Munn Aug 26 '12 at 19:33

Without a minimal working example, all I can do is to guess; the standard behaviour for footnotes in beamer is similar to the one in standard classes: numeric in "regular" text, but alphabetic inside minipage or columns environments, as the following example shows:

\documentclass{beamer}

\begin{document}

\begin{frame}
\begin{columns}
\column{.6\textwidth}
Some text\footnote{a test footnote inside a \texttt{columns} or \texttt{minipage} environment.}
\stepcounter{footnote}
\end{columns}
Some text\footnote{a test regular footnote.}
\end{frame}

\end{document}


This is os because two different counters are in play: footnote for "regular text" footnotes and mpfootnote for footnotes inside minipage or columns. If you want the footnotes inside columns or minipage to be also numbered using arabic numerals you need to redefine the representation for the mpfootnote counter; you will also possibly need to step footnote to maintain syncronicity with regular footnotes; here's the above code with the mentioned modification:

\documentclass{beamer}

\renewcommand\thempfootnote{\arabic{mpfootnote}}

\begin{document}

\begin{frame}
\begin{columns}
\column{.6\textwidth}
Some text\footnote{a test footnote inside a \texttt{columns} or \texttt{minipage} environment.}
\stepcounter{footnote}
\end{columns}
Some text\footnote{a test regular footnote.}
\end{frame}

\end{document}
