你能解釋一下為什麼它不起作用嗎？我剛測試過，添加類似於以下內容的代碼完全正常：
\io1 第一節 \xt MAT 1:1\xt*
--------------
這沒有直接回答你的問題，但你提到了主題索引，然後又提到了通常用於引言大綱的標記（\io#）。如果你混合使用了引言標記（以 \i 開頭的標記）和用於正文的標記（例如 \p 之類），那可能就是問題所在。
請參閱此處，了解如何使用 \k 標記（與術語表中使用相同的關鍵字標記）來佈局主題索引的示例。

Can you explain how it isn't working? I just tested and adding something like this worked perfectly fine:
\io1 First section \xt MAT 1:1\xt*
--------------
Not directly answering your question, but you talk about a topical index and then talk about markers (\io#) typically used for introductory outlines. It's maybe possible that if you're mixing introductory markers (ones starting with \i) along with markers used in regular text (like \p or the like), that that's the problem.
See here for an example of how topical indexes might be laid, out, using \k markers (the same keyword marker used in glossaries).
