latex 中 \frametitles{} 之间的交叉引用

Question

我有一个长投影仪演示文稿，因此我想创建一个\frametitle双向的无编号引用。提前致谢。

    \documentclass{beamer}
%Information to be included in the title page:
\title{Sample title}
\author{Anonymous}
\institute{Overleaf}
\date{2021}

\begin{document}
    
    \frame{\titlepage}
    
    \begin{frame}
        \frametitle{Sample frame title} 
        FIRST TEXT REF TO -> frametitle{APPENDIX}
    \end{frame}

    \begin{frame}
    \frametitle{Sample frame title}
    SECOND TEXT
\end{frame}


\appendix

\section{Appendix Bibliometric Dataset of Chapter 2}

\begin{frame}   \frametitle{APPENDIX} 
    APPENDIX REF TO -> frametitle{Sample frame title}
\end{frame}
    
\end{document}

Answer 1

如果你给你的框架一个标签，你可以使用它\hyperlink{label}{some text}在它们之间跳转：

    \documentclass{beamer}
%Information to be included in the title page:
\title{Sample title}
\author{Anonymous}
\institute{Overleaf}
\date{2021}

\begin{document}
    
    \frame{\titlepage}
    
    \begin{frame}[label=firstframe]
        \frametitle{Sample frame title} 
        \hyperlink{appendixframe}{\beamergotobutton{Appendix}}
    \end{frame}

    \begin{frame}
    \frametitle{Sample frame title}
    SECOND TEXT
\end{frame}


\appendix

\section{Appendix Bibliometric Dataset of Chapter 2}

\begin{frame}[label=appendixframe]
   \frametitle{APPENDIX} 
    \hyperlink{firstframe}{\beamergotobutton{back}}
\end{frame}
    
\end{document}
