Another #emacs interactive function I didn't know...
What's this thing called "shortdoc"?

`M-x shortdoc list`

It gives a list of Elisp functions useful for list manipulation!

Mmm... I think I can add more shortdocs for #Org Element API, in fact it seems rather easy:
```
(define-short-documentation-group org-element-api
"Org Element API"
(org-element-parse-buffer)
;; ...
)
```

Oh hoho! You don't need to do anything in order to make the shortdoc group appear at the proper function help. #Emacs does that for you!

For example: There is a "string" shortdoc group, and string-equal is member of this group. If I do `C-h f string-equal`, the help suggests to look at the "string" shortdocs group.

But the string-equal docstring does not say anything about shortdocs! Surely comes from the shortdoc group definition itself!

I have to learn more! 🤩
