我确信很多人已经问过这个问题，但我找不到正确的答案。
我想跟踪我提供给 tcbtheorem 的标签/键。我不知道遇到此问题的最佳做法，我希望在文档的某个地方有一个部分或章节，但我也希望在 pdf 的边距部分中有标签/键。
我看到了这个想法，最好将标签/键放在 pdf 的边缘部分。
但是当我尝试这样解决时，当我使用 \label{} 时我确实得到了预期的结果（参见下面提供的代码）
还
% Command to automatically display the reference
\newcommand{\autoNameref}[1]{\nameref{def:#1}}
\begin{document}
\tcblistof[\section*]{def}{List of Defenition}
工作正常。
但我在边距部分或其他地方看不到 def:Pi 或 def:TestRef 的给定引用。如果我像这样 \label 它：
{for example Pi\label{def:Pi2}}
我想说，这走错了方向，为什么我在做了之前的所有努力之后还要给所有事情贴上标签。
也许我必须
\usepackage{nameref}
\usepackage{showkeys}
\usepackage{showexpl}
以不同的方式启动它，但我找不到有关此的任何信息。我也在 tcolorbox - manual 中搜索了很多时间： tcolorbox - 手册
我将不胜感激任何提示或解决方案。
感谢您的帮助。
我尝试尽可能缩短我的序言，因为我确信这样是没问题的。

嗯，标签在那里，但它隐藏在 tcolorbox 的标题后面，因为出于某种原因 showkeys 使用了\rlap。您可以将其移动到边距中：
\documentclass[12pt,a4paper]{book}
\usepackage[german]{babel}
\usepackage[T1]{fontenc}
\usepackage{showkeys}
\usepackage{hyperref}
\usepackage[most,many,breakable]{tcolorbox}
\newtcbtheorem[number within=section, list inside={def}]
{Definition}{Definition}{
frame empty,coltitle=red, %to remove the background
title={#2},#1}{def}
\begin{document}
\section{A}\label{test}
\section{B}\label{longertest}
\begin{Definition}{A defined Number }{Pi}
for example Pi
\end{Definition}
\renewcommand*\showkeyslabelformat[1]
{%
\normalfont\small\ttfamily
\llap{\fbox{#1}\hspace{\marginparsep}}%
}
\begin{Definition}{A defined Number }{ratio}
for example the golden ratio
\end{Definition}
\ref{test}, \ref{def:Pi}
\end{document}
