我正在尝试定义自己的简约frametitle风格。我接近我想要的，但我很难获得自动化miniframes的子弹。
请参阅 MWE 以了解更多信息。
是否有任何简单的方法可以使用内置的项目符号导航来beamer miniframes获取我想要的内容？
（也请随意批评我做事的方式，因为这可能不应该做！）

答案1
当没有小节时，不应显示项目符号：你可以使用以下命令测试自己是否位于子部分之外
\ifnum\thesubsection=0当章节或子章节中只有一帧时，不应显示项目符号：如果（子）部分中只有一个帧，则开始结束帧是相同的。这可以通过
\ifnum\insertsubsectionstartframe=\insertsubsectionendframe和来测试\ifnum\insertsectionstartframe=\insertsectionendframe为什么本小节中有 3 个要点：我认为这归结为节结尾不被识别为小节结尾。作为一种解决方法，可以通过测试来发现这种情况
\ifnum\insertsubsectionendframe<\insertsectionendframe
