我正在修改LaTex Beamer主题，在修改页脚文件后，导航符号LaTex Beamer被弄乱了。我怎样才能在每张幻灯片中恢复它们。我尝试使用\setbeamertemplate{footline}{}\setbeamertemplate{navigation symbols}{\insertslidenavigationsymbol}“%\setbeamertemplate{navigation symbol}{\insertslidenavigationsymbol}”，但运气不佳 :( 它根本不起作用。
如果可以的话，请告诉我如何让这些漂亮的导航符号变暗一点。谢谢

要再次添加导航，您必须将其添加到自定义脚注定义中。
\makeatletter
\setbeamertemplate{footline}
{%
\insertslidenavigationsymbol% <-- THE LINE I ADDED
\setbox\beamer@tempbox=\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}

并将导航符号模板恢复为默认值。
\setbeamertemplate{navigation symbols}[default]
要更改导航符号的颜色，您必须设置相应的投影仪颜色：
\setbeamercolor{navigation symbols}{use=structure,fg=structure.fg!80!bg}
\setbeamercolor{navigation symbols dimmed}{use=structure,fg=structure.fg!60!bg}
在我的示例中，我稍微调整了默认混合比以获得更暗的输出。
