The issue of breakable highlighting was addressed in Cool Text Highlighting in LaTeX
But how, in latex, do I highlight text involving math, something like
which, right now, I do with a succession of \texthl and \colorbox.

Is this what you intended?
\documentclass{article}
\usepackage{xcolor}
\usepackage{soul}
\newcommand{\mathcolorbox}[2]{\colorbox{#1}{$\displaystyle #2$}}
\begin{document}
For inline math, one can simply do \hl{colored $a=b$ math}. For display math, the following works:
\begin{equation}
\mathcolorbox{red}{y=\frac{x^2}{q}}+z
\end{equation}
\end{document}
[** EDIT **]
Ok, see \hlfancy below
\documentclass{article}
\usepackage{xcolor}
\usepackage{soul}
\newcommand{\mathcolorbox}[2]{\colorbox{#1}{$\displaystyle #2$}}
\newcommand{\hlfancy}[2]{\sethlcolor{#1}\hl{#2}}
\begin{document}
For inline math, one can simply do \hl{colored $a=b$ math}. For display math, the following works:
\begin{equation}
\mathcolorbox{red}{y=\frac{x^2}{q}}+z
\end{equation}
And for the fancy version: \hlfancy{orange}{colored $a=b$ math}. Now, \hlfancy{green}{colored $a=b$ math}.
\end{document}

2If you want to change the color used in the
\hlcommand provided by thesoulpackage then you can use e.g.\sethlcolor{green}but note the fragility issues mentioned in tex.stackexchange.com/questions/260566/…– JPiJul 12, 2016 at 1:13 -
1This is what I intended. Well, almost. :-)) What I really would like is, instead of setting the color in the preamble which would force me to define one command per color, to define a command for
\hlin which the color is an option, namely something likeinlinecolorbox{<color>}{<text with math>}As for creating a robust command, that's even more beyond me . By the way, the reason\hlhad not worked for me is that instead of using$ $to delimit math, I was using\( \)which soul does not seem to recognize. Jul 12, 2016 at 18:16 -

\hlfancyworks like magic. I wish I could take the time to understand LaTeX instead of sponging. Well, thanks very much for your patience. Jul 12, 2016 at 21:02 -
You may want to look at the todonotes package for other functionality you might like.– JPiJul 12, 2016 at 23:03
You can also use \colorbox instead of \mathcolorbox. Here's an example:
\documentclass{article}
\usepackage{xcolor}
\usepackage{amsmath}
\begin{document}
Here is an equation:
\begin{equation}
\colorbox{yellow}{$E = mc^2$}
\end{equation}
\end{document}
In this example, the \colorbox command is used to highlight the equation with a yellow background. The equation is enclosed in $ symbols to put it in math mode, which is required for equations. You can replace yellow with any other color that you prefer.
