I don't think this either.

Ah... ok. So that you mean by 'new file format'. But we have that already,
it's called '.tex exported by LyX'. We put there a \def\LyX{...} in the
preamble etc.

Being able to typeset something and being able to edit something are
different things. I've been writeng .tex on machines without latex
installed...

But this breaks as soon as different style define 'proof' differently.

I doubt that. All we need is a parser that can read the kind of .tex we
produce. [And of course the panacea is "inset unification" followed by
"re-use the math parser", but I think you got already tired of that song]

You could lock a \mathbf{x} and pass over it with a single <Right>. If the
inset is not locked, it takes three(!) <Right> which is not really nice.

*grin*
No. The reason is really to have a means to make the "additional cursor
positions" that resulted from the "fonts as insets" change unvisible if not
needed. Of course, this is only sensible if the lock state is saved.
