RETURN & ENTER in Unicode

So; here I am bu**ering around in my Devawriter Pro
[ http://andregarzia.on-rev.com/richmond/dwriterpro.html ]
which is in what I, slightly pompously, call its 3rd System Development
Life-Cycle . . .
Anyway . . .
Inside a socking great rawKeyDown Case statement one of the
possibilities runs a bit like this:
case 65293
set the useUnicode to true
set the unicodeText of the selectedText to (numToChar(13) &
numToChar(10))
select after the selectedText
break
now 65293 is the raw key code for the 'Return' key [ the one above the
right-hand SHIFT key ],
so, in theory, when an end-user hits that key they should end up with a
carriage return in the
text field: BUT they don't.
Just to really confuse the issue, when an end-user hits the 'Enter' key
[ over on the right, on
those keyboards that have a number pad ] they get a carriage return:
this seems to make
no sense at all considering that the raw key code for the 'Enter' key is
65421.
So; just "for a laugh" I threw this into the soup:
case 65421
set the useUnicode to true
set the unicodeText of the selectedText to (numToChar(13) &
numToChar(10))
select after the selectedText
break
and that blocked the 'Enter' key as well.
This tells me that my rawKeyDown for those keys is doing "sweet FA", and
merely serving to block
them.
Of course the easy thing to do is just to remove the case 65293 code so
that the
default
pass rawKeyDown
at the end of the switch statement just lets the OS strut its funky
stuff with the 'Return' key
rather than attempting to over-ride it in the app.
-------------------------------------------------------------------------
BUT; this is not entirely satisfying, and I wonder if anyone can tell me
what I should
have in my case 65293 code instead of
(numToChar(13) & numToChar(10))
to get a carriage return?
