Ooops, sorry for the noise: I looked at the AUCTeX documentation, but
not at the right place:
  ┌────
  │ https://www.gnu.org/software/auctex/manual/auctex/Mathematics.html
  └────

IMHO, too bad TeX-electric-math is nil by default...

As an extra question, documentation says:

  By pressing repeatedly $ while the region is active you can toggle
  between an inline equation, a display equation, and no equation. To be
  precise, ‘$...$’ is replaced by ‘$$...$$’, whereas ‘\(...\)’ is
  replaced by ‘\[...\]’. 

But how to get:

- ‘$|$’   with an "unrepeated" `$',
- ‘\[|\]’ with an "repeated"   `$'?

Ah, good to know!

OK.

Thanks!
