Thanks for the explanatory message you sent recently. Attempting to
follow your instructions, I executed the menu item Language > Choose
Language..., which gave me a list of languages and the parameters that
can be changed. For the "Advanced Student" language (which is what I
was using), here are the parameters that I can change: case-sensitive;
output style = constructor/quasiquote/write; fraction style = mixed
fractions/repeating decimals; checkbox: insert new lines in printed
values; checkbox: show sharing in values. However, I don't see
anything that allows me to turn this highlighting feature off.

Searching for "coverage" in the Help Desk documentation leads me to
the "Errortrace: Debugging and Profiling" document, but I don't find
anything that looks useful here, either.

Finally, I read Andrei Estioco's comment and see now that the orange/
black highlighting goes away for whatever lines of code that get
"exercised" when you execute code from the bottom panel, thus showing
you the parts of your code that (so far, at least) have not gotten
"coverage." This is a useful feature, but I've not found any
documentation for how to control it.

If you (or anyone else) could point us newcomers to some relevant
documentation, we would certainly appreciate it. Thanks.
