In highlighting math, JPi defined \hlfancy a breakable box to highlight text involving math.

In How to refer to indexed words, Andrew defined \INDEX and \DEX to refer to indexed words which work fine when the reference is in a tcolorbox or in a \colorbox but not in a \hlfancy box where it causes an error.

To see, uncomment %\hlfancy{yellow}{A reference in an hlfancybox: \DEX[aaaa]{aaaC}} in the following minimum working example:

\documentclass[11pt]{book}

\usepackage{makeidx}
\usepackage{tcolorbox}
\usepackage{xcolor}
%Begin breakable hlfancy boxes. See https://tex.stackexchange.com/questions/318991/highlighting-math
\usepackage{soul}
\newcommand{\mathcolorbox}[2]{\colorbox{#1}{$\displaystyle #2$}}
\newcommand{\hlfancy}[2]{\sethlcolor{#1}\hl{#2}}
%End breakable hlfancy boxes.

  • @ChristianHupfer Here is how if not why: I forgot to enter my password and StackExchange created a new account with the same name and same email address. No idea how to correct things. I wish I could. – schremmer Nov 10 '17 at 17:08

As mentioned in the documentation of soul: Some things don't work. If you want to use such command inside a soul command you must hide them inside a \mbox. And yes this prevents line breaks for this command and so is not a solution for longer texts:

  • Fisher Of course it doesn't break inside the mbox---so maybe you should change your wording above, but it sure does exactly what I needed. Thank you very much. – schremmer Nov 25 '17 at 17:59
  • A lot of people complain later that text doesn't break in a box, so I thought it would better to say it directly. – Ulrike Fischer Nov 25 '17 at 18:39
  • I meant that, since it doesn't not prevent the rest of the text in the hlfancy box from breaking, I would add "in the mbox" to " this prevents ... longer texts". But then, that's just me and, anyway, it worked fine for me. Thanks again. – schremmer Nov 26 '17 at 19:44
