Which node I turned to only after posting the above. Sorry. Greenhorn
here.

I assume that this can be added to my .emacs or evaluated in a lisp
buffer. I will try both. Although I have been warned against it I would
like to make the changes directly to the latin-post.el. Could I get away
with something like:

(quail-define-rules
[...]

 ("Y-" ?#x0232)  ;;; I tried to copy paste these but they were corrupted
by Outlook Express. (Maybe it's "\x0233" or some other combination
 ("y-" ?#x0233)   ;;; of slashes, hashes, or single or double quotes)

[...]

Thanks. I did read this since I knew it was pertinent to my problem but
I understood dimly if at all.
