@MartinSleziak I changed the answer, thanks. Feel free to alter it further.

@quid Thanks for the edit.

I wonder whether some of the related posts could/should be closed as duplicates.

But I suppose this can simply go through the usual review process.

Perhaps suitable duplicate targets are the question mentioned above (where the answer mentions saves). And maybe this post, too - it has an answer mentioning following: Is there any way to add a bookmark to any answer of a question?

I have cast a close vote here - we'll see in the review whether others agree or not: Is there a way to save the favorite answer?

In this case, the question was tagged discussion - so it went through immediately, because of dupehammer: Why isn't there any option for favourite ANSWER?

Oh, I did not realize that editing the duplicates list bumps the question.
