And yet not one mention of LyX
That'll probably be because LyX is quite emphatic about the difference between presentation and content, so people think it's *hard*?
What Word has done is trained a generation of users who have never learned the difference between the two. Although it has had for years the capability of requiring the use of a style it does not have the ability to mandate it. Further, it is a program which I strongly suspect most people are never taught; instead, they're sat in front of it and told to get on with it... which is never going to end well.
The fact that probably ninety-five percent of the users never use more than a tiny fraction of its capabilities no doubt adds to the mess.
And of course, what Word does, Libre/Free Office also have to do, because people expect similar functionality instead of sensibly looking at what they (the users) actually do and finding a program that just does that.
As M0rt demonstrates above, Word in an immensely complex program with dozens of ways of achieving the result, many of which are either surprising then next time you use them or just plain wrong.
So yes, I'm with Charlie - a plague on all their houses!
