这个答案提供了出色的“粗糙文本突出显示”。不幸的是,我遇到了一个奇怪的故障:
我从链接中直接获取了源代码,并将 和 之间的内容\begin{document}
替换\end{document}
为
{replacing} \highlight{$g$} {by} \highlight{$g^{-1}$},
然而,由于原始代码很长,因此 MWE 很长:

答案1
由于我对 SOUL 了解不多,我想不出快速修改和记录突出显示的文本长度的方法。因此,我修改了随机步骤装饰,因为它太短,无法包含在序言中。

\state{step}[auto end on length=0.5\pgfdecorationsegmentlength, % This was 1.5 now 0.5
auto corner on length=1.5\pgfdecorationsegmentlength,
width=+\pgfdecorationsegmentlength]

\pgfpathlineto{
