Find "where used" things

At different pages, I have links referring to other web pages (outside my pages). Some of them are used more then one time.
When I have to change the linked page, I would like to have a tool that scans my pages and reports me where the requested link is used.
May be such a tool exists but I was not abble to find it.

If you’re referring to code, there’s a search bar:

Thanks for the idea. I tested. It is a one part of what I look for, it seems just to search in code programs, not in pages. Unfortunately, it does not search in pages where I have some text or buttons with the link I am looking for.

I don’t think there’s currently a way to do it.
Maybe someone else knows.
