Quick LaTex: Footnotes with no Counter
Published on
Updated on
Let’s say there’s a scenario where you want to have a footnote, but you don’t want a counter associated with it. In order to stay consistent with the document style, the solution should use \footnote within its implementation.
The solution: Define \blfootnote{text} in the preamble.
\newcommand\blfootnote[1]{
\begingroup
\renewcommand\thefootnote{}\footnote{#1}
\addtocounter{footnote}{-1}
\endgroup
}
This makes use of the footnote command while also re-adjusting the footnote counts so that our variant doesn’t increase it. We can then use this command within the document. Here’s a beamer example:
\begin{frame}{Some Topic}
This is where I explain some topic.
\blfootnote{Numberless Footnote}
\end{frame}
Complete Minimal Example:
\documentclass[aspectratio=169]{beamer}
\usepackage[utf8]{inputenc}
\usetheme{Copenhagen}
\newcommand\blfootnote[1]{
\begingroup
\renewcommand\thefootnote{}\footnote{#1}
\addtocounter{footnote}{-1}
\endgroup
}
\begin{document}
\begin{frame}{Some Topic}
This is where I explain some topic.
\blfootnote{Numberless Footnote}
\end{frame}
\end{document}
