章节标题不适合投影仪中的目录

Question

因此，我的演示文稿中有一个部分的名称较长。在幻灯片上，我只需使用 \small，它就可以适合幻灯片，但在目录中它不会“中断”，只是继续切断部分的标题：有没有办法让它适合，或者继续在部分下面？

Answer 1

使用 latex-ps-pdf 编译hyperref无法直接断开链接。您可以使用以下代码片段：

\makeatletter
\providecommand{\H@@footnotetext}{}
\makeatother
\usepackage{hypdvips}

hyperref或者你可以使用选项加载包breaklinks=true

\documentclass[hyperref={breaklinks=true}]{beamer}

Answer 2

使用可选参数\subsection为子部分指定别名。例如：

\subsection[Short but descriptive name]{A very long subsection that doesn't want to collapse into two row, but rather goes on and on and on}
