\colorbox{}{}我在与下划线结合使用时遇到一些问题。
清单将顺利编译并正确突出显示文本，但只要我在要突出显示的文本中出现下划线，我就会收到 100 次相同的错误。
pdflatex> l.215 ...red_3 \!\colorbox{lightred}{Man_3}!
pdflatex> . )
pdflatex> ! Extra }, or forgotten $.
pdflatex> <recently read> \egroup
我尝试用斜线转义“_”，但没有帮助。

上面的代码按应有的方式呈现，但只要我添加“_”，它就不起作用。
有人知道我如何在示例中的带下划线的单词上使用颜色框吗？
答案1
转义下划线就可以了：
笔记：
- 您有
escapechar = \!定义要转义为 LaTeX，因此下划线是需要转义的特殊字符之一。否则它将被解释为下标。 - 此外，在撰写平均能量损失，您应该尝试消除重现问题不需要的不必要的选项和包。
