我正在写一些包含许多章节的笔记。在此文件的每个章节末尾，我想插入一个练习列表，标题如下：
Problems - Section x.y (x = chapter, y = section)
\begin{exercise}
blah blah blah
\end{exercise}
我可以使用 \label 命令来执行此操作，例如
\section{NameSection}\label{secx.y}
bla bla bla
Problems - Section \ref{secx.y}
\begin{exercise}
blah blah blah
\end{exercise}
有没有办法使用诸如 \lastchapter.section 或 \current.chapther.section 之类的命令来代替 \ref{secx.y} ？
我正在使用超链接。

一次运行即可完成。您几乎可以将任何内容输入到文本输入中。
它可能并不总是适用于section.\thesection，这取决于\thesection的定义方式。如果您查看 下的辅助文件，\contentsline您将找到锚点名称section.1.1（例如）。这就是您需要为 重现的内容\hyperlink。
