我在课堂上用过\usetheme{PaloAlto}它作为演示文件beamer。如何从第一张幻灯片（标题幻灯片）的左侧删除目录（各节和子节的标题）？
\documentclass{beamer}
\usepackage[utf8x]{inputenc}
\usetheme{PaloAlto}
\usecolortheme{seahorse}

\define@key{beamerframe}{t}[true]{% top

\everypar{\global\let\beamer@firstlineitemizeunskip=\relax}}
}
\makeatletter
\setbeamertemplate{sidebar \beamer@sidebarside}%{sidebar theme}
{
\beamer@tempdim=\beamer@sidebarwidth%
\advance\beamer@tempdim by -6pt%
\insertverticalnavigation{\beamer@sidebarwidth}%
\vfill
\ifx\beamer@sidebarside\beamer@lefttext%
\else%
\usebeamercolor{normal text}%
\llap{\usebeamertemplate***{navigation symbols}\hskip0.1cm}%
\vskip2pt%
\fi%

\item The problem is solved

您可以重新定义此框架的侧边栏模板，或者，作为一种快速技巧，只需更改标题页上的部分和子部分的字体颜色以匹配背景即可。这样它们就不再可见了。
还请注意，您不需要\usepackage{hyperref}使用投影机。
\documentclass{beamer}
