return and enter keys in emacs 21.3 on MacOSX 10.2

[tiagohenriques@lycos.co.uk (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
