减少目录间距（投影仪）

Question 1

内部命令\beamer@sectionintoc（在文件中定义beamerbasetoc.sty）控制如何在目录中排版章节条目；它发出一个\vskip1.5em命令，在章节条目之间添加垂直间距。借助该etoolbox软件包，您可以轻松修补命令以减少垂直间距。一个小例子：

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\beamer@sectionintoc}{\vskip1.5em}{\vskip0.5em}{}{}
\makeatother

\title[Short Title]{My very long title that doesn't fix into the footer}
\author{Me}
\date{\today}
\beamertemplatenavigationsymbolsempty
\setbeamertemplate{footline}[frame number]
\usetheme{CambridgeUS}

\AtBeginSection[]
{
\begin{frame}
\frametitle{Outline}
\tableofcontents[currentsection, hideothersubsections]
\end{frame}
}

\begin{document}

\maketitle
\clearpage

\begin{frame}

\tableofcontents[hideothersubsections]

Question 2

对于像我一样寻找如何减少subsectiona 的末尾section和下一个section目录条目之间的空间以及 OP 的问题的人来说，答案是@Gonzalo Medina可以这样调整：

\makeatletter
\patchcmd{\beamer@sectionintoc}{\vskip1.5em}{\vskip0.5em}{}{}
\patchcmd{\beamer@sectionintoc}{\vfill}{\vskip0.2em}{}{}
\makeatother

其中，\vfill命令重新定义为\vskip可以修改为您想要的任何值。之前（不重新定义\patchcmd）：

添加上述\patchcmd命令后（OP 的 MWE 不允许，hideothersubsections对于我的目的来说这不是必要的）：

我希望这对那些与我一样不知道该怎么做的人有帮助！
