删除导航符号，但保留左右箭头

2024-5-23 • tag-icon

这些按钮让我很烦，因为点击它们什么也得不到。但是旁边的小箭头可以帮我导航。问题是箭头在脚注的黑色背景中总是不可见的。有没有办法在隐藏按钮的同时突出显示箭头？谢谢。

您可以通过设置另一个 beamer 模板将导航符号减少为仅幻灯片导航，并通过更改来更改颜色navigation symbols dimmed。

\documentclass{beamer}

\defbeamertemplate*%
  {navigation symbols}%
  {reduced}%
  {\hbox{\insertslidenavigationsymbol}}

\setbeamercolor{navigation symbols dimmed}{fg=red}

\begin{document}

\begin{frame}
\end{frame}

\end{document}
