How could I mark all appearances of some symbols

#1

I want mark every appearance of some symbols, each symbol with a uniq style(e.g. background color).

How could I do?

That would require coding a new package. You would have to find the symbols and add highlights. Not too hard actually.

Thanks for reply!
I would like coding some useful packages, but I’m poor in Atom currently :grin: .
If you find a package similar, let me know. Or have you any more tips for me to make it out?
