hash tag links

[Solar-Simon]

Is your feature request related to a problem? Please describe.
If you use headings, a # symbol is displayed and the alt “Link to this section”. However, this is relatively obsolete, as the hash and the heading are already on the screen.
To make the feature useful, hash links should work in the rest of the text and be distinguished from external links.
I did not manage to place a link to a # anchor elsewhere. They were displayed like external links instead.

Describe the solution you'd like
I would like an automatic recognition that it is an internal #-link.Then the underlying word should simply look like a link (word + underline), or it would even be good to display a # symbol in front of the word.

Additional context
mookup, what it could look like.
