It would mean that these keystrokes meant different things depending on what machine I was logged into.  I would have to relearn editing skills I learned over 30 years ago.  I couldn't use Aquamacs if you changed this fundamental meaning.

Could you clarify please: do not change them from their Emacs 23 settings?
In Emacs 23, all of these apply to the visual line (visual-line-mode = soft word wrapping on).  That's what the commands do in Emacs 23.  

This is different from Emacs 22, where C-a moved to the beginning of the (long) buffer line, no matter what the wrapping was.  Native word wrapping didn't exist (longlines-mode excluded).  When I introduced word wrapping in Emacs 22 in one of the Aquamacs 1.x versions, I took care to give C-a, C-e, C-n, C-p their meaning based on visual lines, based on user feedback.

So do I understand you correctly that you want the bindings to be same in 2.x and in 1.x, i.e. as in Emacs 23?
I'm confused as you mention macros, which seem to require buffer-based semantics.

Right, I forgot about that, which means we'll have to use different bindings there. Thanks.
