+title: "Quick LaTex: Footnotes with no Counter"

+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}
+
+```
