Oops, mea culpa. You're right, I mixed both thinking Latex and Tex were quite equivalent in term of style rendering. I never bothered looking into Tex, I just wrote some Latex classes (and documents, of course).

Oh but Word wasn't on my mind at all when I commented. I even followed the link on keynote to see what was the reference (since I never looked at keynote or iLifexxx documentation).
