我在文中加入了边注，以帮助读者找到文中的重要术语。
现在，我应该把 marginpar 放在哪里才能与 term 保持一致？
Let us define \marginpar{Ipsum}\emph{Ipsum}: ...
或者
Let us define \emph{Ipsum}\marginpar{Ipsum}: ...
（补充：把它放在冒号后面会不会弄乱什么？）
Let us define \emph{Ipsum}:\marginpar{Ipsum} ...
答案1
我刚刚尝试过实验，尽管我的实验可能过于简单，但只要项目和边距之间没有空格，我就无法检测到这三种情况的任何差异。
我的实验是以下代码：
\documentclass{article}
\newlength\shove
\setlength{\shove}{23.57pt}
\begin{document}
How much is that doggie in the window?\hspace{\shove}
The one with the waggly tail?
How much is that doggie in the window?
I do hope that doggie's for sale!
How much is that doggie in the window?\hspace{\shove}
The one with the waggly tail?\marginpar{That's ``tail'' not ``tale''}
How much is that doggie in the window?
I do hope that doggie's for sale!
How much is that doggie in the window?\hspace{\shove}
The one with the waggly \marginpar{That's ``tail'' not ``tale''}tail?
How much is that doggie in the window?
I do hope that doggie's for sale!
How much is that doggie in the window?\hspace{\shove}
The one with the waggly tail\marginpar{That's ``tail'' not ``tale''}?
How much is that doggie in the window?
I do hope that doggie's for sale!
\end{document}
通过反复试验，\shove可以在此处添加的最大空间是多少，而不会将“尾巴？”推到下一行。这三个在定位和间距方面看起来完全相同。
（当然，关于把它放在哪里，可能存在争议。语义原因，但我会把这个问题留给别人，因为我不知道在这种情况下适用的硬性规定，所以我的意见只是：一种意见。）
