Some time ago there was a change to the icons displayed next to a question, and the favourite icon was replaced by a bookmark icon.
However, there is nothing in any of the site help pages explaining what either of the above do. It would be useful if we had a couple of new help pages:
One that explains what all these icons around questions and answers do when you click on them.
For "Bookmark this question" the explanation should include how a user finds their bookmarks.
Another that explains what the "follow" link does (and how to find posts you are following).
Note: there is already a help page that explains the "flag" link. For consistency we should have help pages for the other links.
Justification: we can link to the help pages when assisting new users in comments. For example I have an AutoReview comment:
Please don't leave answers stating that you have the same problem as the one described in the question. If you have sufficient reputation, you may upvote the question. You can also "bookmark" it or "follow" it (which will notify you of any new answers).
I would like to be able to link to help pages about "bookmark" and "follow" in my comment.
Bonus Feature Request: please also add magic links for the new help pages.
