Re: REDO ?

[Richard Stallman]

    A-z `aquamacs-undo'   (similar to `undo-only')
    A-Z `aquamacs-redo'
    C-_ `undo'

    A-z and A-Z the standard keys on the Mac. Note that A- is bound to  
    the "command" key.

    This is probably not something that can be done in Emacs.

That is true.

By the way, since Aquamacs ias a modified version of GNU Emacs, it
does come out of GNU.  Please do not constrast "GNU Emacs" and
"Aquamacs", because that would imply that only the former comes from
GNU, and would deny us credit.  It is very unfriendly.
