如何在投影仪幻灯片底部添加文本（例如参考）？
我只想要文本，不需要 bib 或 biblatex（对我来说现在太复杂了）。
这是我的例子：
\documentclass[14pt,t]{beamer}
\usepackage{graphicx}
\title{Slides}
\author{Username}
\begin{document}
\maketitle
\begin{frame}
\frametitle{Section 3}
\begin{itemize}
\item line1
\begin{itemize}
\item item1
\item item2
\item item3, here I would like to have a reference below, at bottom of slide, in the box on left side.
\end{itemize}
\end{itemize}
\end{frame}
\end{document}

使用脚注：
\documentclass[14pt,t]{beamer}
\usepackage{graphicx}
\title{Slides}
\author{Username}
\begin{document}
\maketitle
\begin{frame}
\frametitle{Section 3}
\begin{itemize}
\item line1
\begin{itemize}
\item item1
\item item2
\item item3, here I would like to have a reference below, at bottom of slide, in the box on left side.\footnote{text at bottom of slide}
\end{itemize}
\end{itemize}
\end{frame}
\end{document}
