I would prefer this not change.

Changing the meaning of C-e, C-a, C-n, C-p would make Aquamacs  
unusable for me.  It would break saved macros.  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.

You tried this once, and people complained, and you changed it back.   
I thought this idea had been put to rest.

If you wish to bind new keys that have no current meaning, go for it.

(In Aquamacs 1.9, C-h-k C-S-A pops up a help window that says that it  
is the same as C-a, but in fact it does something different: C-a goes  
to the beginning of a line but C-S-a goes to the beginning of the line  
and highlights from the old point to the beginning of the line.)
