在突出数学其中，JPi 定义了\hlfancy一个可破坏的框来突出显示涉及的文本math。
在如何引用索引词，安德鲁 (Andrew) 定义了\INDEX并\DEX引用索引词，当引用位于tcolorbox或在\colorbox但不在\hlfancy会导致错误的框中时，这些索引词可以正常工作。
要查看，请取消注释%\hlfancy{yellow}{A reference in an hlfancybox: \DEX[aaaa]{aaaC}}以下最小工作示例：

正如 soul 文档中所述：有些东西不起作用。如果您想在 soul 命令中使用此类命令，则必须将它们隐藏在 \mbox 中。是的，这可以防止此命令出现换行符，因此对于较长的文本来说这不是一个解决方案：
