return and enter keys in emacs 21.3 on MacOSX 10.2

[Tiago Henriques]

Hi,

I'm using emacs 21.3.50.5 with MacOSX 10.2.3 (Jaguar, update 3).
Unfortunately I'm having a bit of a problem with, since my Return key
doesn't seem to work correctly under Jaguar. Using my 500MHz iBook,
the only way I can make it work is by pressing Fn-Return or Ctrl-M,
which is annoying. Using an external USB  keyboard I still have the
same problem, the only difference being that the KeyPad Enter key
seems to be recognized as return.

I understand that these 2 separate keys correspond to 2 different
keycodes, and usually are associated with the following ascii
characters:

Return: ascii 13
Enter: ascii 3

It seems emacs is only accepting ascii 3 for Return, instead of
accepting 13 or both. How can I configure my .emacs file so that it
maps Return to Enter, making the  Return key emit ascii 3? Or am I
looking at it the wrong way?

I've googled for the answer for one and a half days, and was unable to
find a solution.

Thanks in advance for any advice,

Tiago Henriques

PS: In case of doubt, here is my .emacs file:

(global-set-key [(alt z)] 'undo)

(setq load-path (cons "~/Documents/emacs/" load-path))
(setq load-path (cons "~/Documents/emacs/rozenberg/" load-path))
(setq auto-mode-alist
      (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist
      (cons '("python" . python-mode)
            interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)
(add-hook 'python-mode-hook
          '(lambda ()

(load "py-mode-ext.el")

Are you running Emacs under a window system (Aqua in this case, I
guess)?

What does C-h l print after you hit the return key?

What does C-h c <return> print?

What do C-h l and C-h c show for the "other" return key?

C-h c <return>:
<return> is undefined

C-h c <keypad enter>:
RET (translated from <kp-enter>) runs the command newline

After I type these 2 commands, C-h l shows:
(...) C-h c <return> C-h c <kp-enter> C-h l

It seems that the return key is unassigned. How can I assign it to run
the command newline, similarly to the keypad-enter key?

I added the following line to my .emacs file:

(global-set-key [return] 'newline)

and now I can use the main keyboard's <return> key as normal when
typing in a standard buffer. However, when I use the mini-buffer (e.g.
when visiting a file with C-x C-f) it doesn't seem to work, while both
C-m amd <keypad enter> do work.

It seems that instead of assigning the command "newline" to the return
key I need to translate <return> to RET, as emacs is apparently
already doing with <keypad enter>:

C-h c <keypad enter>:
RET (translated from <kp-enter>) runs the comand newline

How can I do this translation?

Been there recently.  I think this should help:

  (define-key function-key-map [return] [?\C-m])

OTOH, I copied this line from lisp/term/mac-win.el, and that file
should be loaded on Emacs startup, as I understand it.


so long, benny

Great tip! That one line seems to have solved the problem. Thanks a lot!
