From emacs -Q:

Type several lines of all-caps words in the scratch buffer, one word per
line, e.g.:

ABC
DEF
GGG

M-x replace-regexp or query-replace-regexp.
    regexp: \(.*\)
    replace: \,(downcase \1)

Emacs reports all occurrences have been replaced, but nothing has
actually changed.

Oddly, the same recipe does work for \,(capitalize \1) (using initial
lowercase words of course)

Shoot, sorry for the noise, that does the trick. And it was right there in
the documentation. Thank you for the quick reply.
