beamer footnote not showing

Question

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.

Answer 1

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.
