[racket] Alt/Option key as meta on Mac

Hi, I tried searching the archives for an answer, but without success:

Ss there a way to make the alt/option key on a Mac function
as an Emacs meta key?   The current default is for the cmd/apple key
to be the meta key, which is not the same as the default for Emacs
(Aquamacs) on the Mac.

If I turn that off the option under Editing > General, the meta
functionality does not switch to the alt/option key.   I also tried
playing with the Enable Keybindings in Menus option, but that did not
seem to have an effect.

Thanks, -CR
