I would like to underline all occurrences of a factor that appears in a text, e. g. all occurrences of aba
in text=abaababa
If I use underline, I won't see clearly the three occurrences so what I need is a package which allows me to use overlapping \underline{}
.
I did it in the past and it worked well (it's therefore feasible) but I'm getting old now and I don't remember how I did it.
