分叉 PDF：在演讲期间选择“计划 B”

Question

我认为这是一个新手的问​​题，但无论如何。有时很难根据未知的地点和听众来衡量演讲的时间。出于这个和其他原因，我想巧妙地发起一个隐藏的“B计划”（或者，为什么不，更长的计划 C）在我的演讲中。具体来说

问题：是否可以生成 PDF 以便人们在演讲时做出决定。也就是说，如果在演讲的某个时刻，人们注意到时间不够了，可以手动选择较短的幻灯片序列？

（最佳解决方案可能是有足够的演讲练习——但这不是我的情况）

Answer 1

综合考虑这些建议，答案可以归结为以下代码。在这里，人们\hyperlink在战略幻灯片中引入了一对链接（带有）。在幻灯片上，人们可以看到剩余时间并决定以下三个选项之一：继续正常演示；缩短演示时间B 计划，可以通过跳过证明来进一步减少；或者走更长的路径，计划 C单击框架标题。
