I agree, inserting macros and environments behave differently :-(

I think this is "future past" ;-)  AUCTeX manual says this[1]

  User Option: TeX-insert-macro-default-style

      Specifies whether TeX-insert-macro will ask for all optional arguments.

      If set to the symbol show-optional-args, TeX-insert-macro asks for
      optional arguments of TeX marcos, unless the previous optional
      argument has been rejected. If set to show-all-optional-args,
      TeX-insert-macro asks for all optional
      arguments. mandatory-args-only, TeX-insert-macro asks only for
      mandatory arguments. When TeX-insert-macro is called with prefix
      argument (C-u), it’s the other way round.

So the comment above doesn't apply anymore.

Would it make sense to say:

  • C-u C-c C-e modifies the document
  • C-u C-u C-c C-e toggles the arguments query

?

Best, Arash

P.S.: I think we also have an issue with inserting environments when
region is selected, I will try to make a recipe in another mail.
