This is a follow-up question. A working example of highlighting the first reference in text can be found in
However, there is an open question on how to handle lists of references. For now, the answer neglects lists and does not keep track of their occurrence. I require highlighting the complete list and keeping track of the highlights as if the references were standalone. So if I say
I would get highlighted
Equations (1) to (3)
If I then reference to one of these equations again, they won't be highlighted as they were already highlighted in the list?
Thanks for your help and a happy new year to you all!
