I should have properly used the constant wdListNumberStyleNumberInCircle
instead of wdCaptionNumberStyleNumberInCircle (though they are the same
value, 18).
Most other possible wdListNumberStyles are available from the user
interface, or refer to Asian, Hebrew, Arabic, ... numbering systems.
I can see only three others that might be of interest for Latin numbers, and
aren't available from the user interface:
-- wdListNumberStyleGBNum1 for 1. 2. 3. -- though you could get much the
same result with a dot in the numbering format,
-- wdListNumberStyleGBNum2 for (1) (2) (3) -- though you could get much the
same result with parentheses in the numbering format, and
-- wdListNumberStyleArabicLZ (for numbers that are spaced far apart).
BTW, I just noticed that the numbering for cardinal text, ordinals, ...
depends on the language formatting.
So if you format a list numbered "First Second Third ..." in French, you get
"Premier Deuxième Troisième ...".
Wasn't aware of that before :-o
