在 Beamer 中停止幻灯片滚动

我在演示结束时有一些备用幻灯片，可通过超链接访问。因此，我想在最后一个“实际”幻灯片处“停止”幻灯片的滚动（通过单击 PageUp / Page Down 或旋转鼠标滚轮完成），以防止我在演示过程中错误地显示附加幻灯片。这可以吗？我不确定我是否表达清楚了...

梅威瑟：

\documentclass{beamer}
\begin{document}

\begin{frame}[label=mainBody]
txt 1

\hyperlink{accessorySlide}{\beamerbutton{jump to accessory slide}}
\end{frame}

\begin{frame}
txt 2

\end{frame}

\begin{frame}
Thank you
\end{frame}

\begin{frame}[label=accessorySlide]
accessory information 
\hyperlink{mainBody}{\beamerbutton{jump back to main body}}
\end{frame}


\end{document}

我希望在演示模式下，无法滚动超出“谢谢”幻灯片

这是基于上一个关于循环播放最后一张或两张幻灯片的问题的答案。相反，当前进到最后一张幻灯片的副本时，它会跳回到最后一张幻灯片。到目前为止，我只在 Windows 版 Adob​​e Reader X 中测试过它（在演示模式下）。

\documentclass{beamer}

\begin{frame}[label=TheEnd]
    Thank you
\end{frame}

这可以通过使用 PDF 规范的子页面导航功能来实现。它适用于Acrobat 阅读器 DC并要求全屏（Ctrl-L）模式。

请注意，辅助幻灯片的反向链接（GoBack操作）在 A-Readers X 和 XI 中不起作用。GoBack幸运的是，它在 AR-9 中起作用，并且又回到了 AR-DC。
