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.
|
|
|
|
```latex
|
|
\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:
|
|
|
|
```latex
|
|
\begin{frame}{Some Topic}
|
|
This is where I explain some topic.
|
|
\blfootnote{Numberless Footnote}
|
|
\end{frame}
|
|
```
|
|
|
|
Complete Minimal Example:
|
|
|
|
```latex
|
|
\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}
|
|
|
|
```
