Carbon Emacs binding to Enter key

Carbon Emacs binding to Enter key

[Tiago Maduro-Dias]

Hi!

I've recently "discovered" the usefulness of the enter key (the one 
next to the arrow keys and the space-bar), at least on my laptop's 
keyboard, as an alternative to the regular return key. But I also seem 
to have encountered an interesting issue (read "feature"?) with Carbon 
Emacs 21.3.50 (on Mac OSX Panther).

When I press the key, the event seems to be attached to C-c. In fact, 
pressing it twice will result in the obvious C-c C-c and C-h c ends up 
with "Describe key briefly: C-c-" on my minibuffer (waiting for another 
event).

If I run both the original emacs-21.2.1 or emacs-21.3.50 from 
Terminal.app (with either emacs -nw or emacs -q -nw), the enter key 
will behave as expected (by me at least). If I use the faithful xterm, 
then the behaviour just described for Carbon Emacs happens again. This 
makes sense to me, since Terminal.app is interpreting the strokes, and 
uses the smilingly standard macosx interpretation for the particular 
key.

So, how can I go about forcing the key to bind to what I want it to? 
(character 13, newline, or something of the sort)?

Thank you in advance,

Tiago Maduro-Dias.

You may need a package like ucontrol
	<http://www.gnufoo.org/ucontrol/uControl1.4.4.dmg>

Most Mac OSX Emacs users use this to rebind the caps lock key into control.

It also supports rebinding of the enter key into other things; a common 
usage is to rebind it to 'fn', so that page-up and page-down can be done 
with one hand.

This must be keyboard specific, I guess.  On my iMac using the
standard keyboard, Control = control and Pg UP/Pg Dn work fine for
one-handed paging.  Perhaps there are special issues for
PowerBook/iBook keyboards of which I am unaware.

Good point.  The issue of Pg Up/Pg Down is specific to PowerBooks,
which lack this key.  So, paging through documents with one hand is hard.

The Control/CapsLock problem is common to most Mac (and Windows) 
keyboards, however.  The Control key is somewhere below the left shift 
key.  The key immediately above the left shift key, which should be 
Control, is Caps Lock.  uControl enables remapping on the Mac.  On 
Windows, the same thing can be done via the registry.
