在减少目录间距（投影仪）答案是使用带有代码的 etoolbox
\patchcmd{\beamer@sectionintoc}{\vskip1.5em}{\vskip0.5em}{}{}.
这对我来说可以减少 Beamer TOC 中部分条目之间的空间，但对子部分条目之间的空间无效。修补 \beamer@subsectionintoc 是可行的方法吗？我试过了
\patchcmd{\beamer@subsectionintoc}{\vskip1.5em}{\vskip0.5em}{}{},
但这不起作用。
以下是 MWE samcarter 请求的：

注释掉\setlength{\parskip}{\smallskipamount}似乎会产生正确的结果。
