How foolish of me to have not suspected that the key codes for ASCII 
control characters would "obviously" be found in NSText.h, while all 
the other function key codes are in NSEvent.h  :|

Another issue closed, thanks to Ricky Sharp.

Revised, tested code, responding to both 'return' and 'enter', is below.

- (void)keyDown:(NSEvent*)event {
    NSString *s = [event charactersIgnoringModifiers] ;
    unichar keyChar = 0 ;
    BOOL didDo = NO ;
    if ([s length] == 1) {
        keyChar = [s characterAtIndex:0] ;
        if ((keyChar == NSCarriageReturnCharacter) || (keyChar == 
NSEnterCharacter)) {
            // Unless editing is already in process, which is not the
            // case we're trying to handle here, an entire row will
            // be selected and therefore [self selectedColumn] will
            // be the "no selection" indicator, -1. So, we edit column
            // 0.  If the user wants a different column, they can
            // easily tab to it.
            [self editColumn:0
                            row:[self selectedRow]
                      withEvent:nil
                      select:YES] ;
            didDo = YES ;
        }
    }

    if (!didDo) {
        [super keyDown:event] ;
    }
}
