Unnumbered footnote in Beamer

Postby asafw » Thu Jan 04, 2018 10:43 am

Hi there,

What is the simplest way to insert an unnumbered footnote in a Beamer slide?

I found an answer online which suggests to define

\newcommand\blfootnote[1]{%
\begingroup
\renewcommand\thefootnote{}\footnote{#1}%
\addtocounter{footnote}{-1}%
\endgroup
}

but the footnote does not show at the bottom of the slide when I try to use it.


Thanks so much,
Asaf

Crosspost in TeX.SX.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Hi Asaf,

your code works as expected. When I use it, the footnote text appears at the bottom. Here is an example that shows it with your code. Just click on "Open in Overleaf" to easily verify it in the online LaTeX compiler. I tested with several beamer themes such as Warsaw and Singapore.

  1. \documentclass{beamer}
  2. \usetheme{Singapore}
  3. \usepackage{blindtext}
  4. \newcommand\blfootnote[1]{%
  5. \begingroup
  6. \renewcommand\thefootnote{}\footnote{#1}%
  7. \addtocounter{footnote}{-1}%
  8. \endgroup
  9. }
  10. \begin{document}
  11. \begin{frame}
  12. Text\blfootnote{Unnumbered footnote} \blindtext
  13. Text\footnote{Numbered footnote}
  14. \end{frame}
  15. \end{document}

The reason, why it doesn't show up on your slide, is in your other code. Or the slide is already too full. Can you post your code (Infominimal working example) that shows the problem?

Thanks so much Stefan!
Looks like it didn't work for me earlier due to incompatibility with "setspace" and "subcaption" packages.

Thanks again,
Asaf
