我在 Mac 上使用 LyX 2.2dev 以及定理 (AMS)、定理（AMS 擴展）、按節數方程式和定理（按節編號）模組。我將 \swapnumbers 放入 LaTeX 序言中，但數字仍然沒有交換。
另外，似乎定義一個新的定理或定義會得到一個新段落的縮進，而我希望定理的編號從最左邊的地方開始。

答案1
感謝您精彩的 MWE 和明確的問題！
這裡的問題是你需要在 LaTeX 序言中靠近頂部的地方放置一些東西。 LyX 中的序言只是整個 LaTeX 序言的一部分。碰巧的是，您載入的 LyX 模組貢獻的前導碼部分位於用戶前導碼之上。正如 @barbara beeton 在評論中所述，您需要\swapnumbers將命令放在\newtheorem命令之前。在 LyX 中，您可以透過幾種不同的方法來解決此問題。一種方法如下。我們定義了一個“本地佈局”（閱讀“幫助”>“自訂”以獲取更多資訊），它恰好在其他模組之前輸出。
為此，請前往“文件”>“設定”>“本機佈局”並輸入以下內容：
Preamble
\swapnumbers
EndPreamble
然後按“驗證”。然後按“確定”。就是這樣。
這會產生以下 .lyx 檔案（我的 LyX 開發版本比您的版本稍新，因此更新並重新編譯或僅用 479 替換 480 應該可以）：
