Can you provide an example? I could not find a list of all the
programming major-modes in emacs manual.
Called "C-h f mhtml-mode" for instance, which never discusses any
indentation rules. For embedded JS, the documentation says that
code elements are indented using the rules from ‘js-mode’. But
then, doing "M-h f js-mode" does not describe any indentation
rules.

By the definition of "re-" meaning "again"? Thus re-indent
corresponds to indent again. Ok
