When I tried fixed(0)->accessible(0)
TeXmacs crashed before opening the first window...

That is much better!

That works really well !!
I defined a new tag next-line2:
<\assign|next-line2|<next-line>>
This works better than expected: on inserting <next-line2> I only see
a line break, without the ugly representation of the break, and
The cursor shows up on the next line!! Really cool.
But When I also added
<\drd-props|next-line2|accesible|none>
The cursor would still enter the next-line2 tag. But that's not so
bad, because you can see where it is.

Ok, I started using <next-line> ;)
But I would much prefer if <\around> would allow line breaks.... I
haven't figured out how to do that.

I'm not sure I fully understand what you mean... Do you mean that when
I copy and paste as verbatim, for example,
<next-line> is not converted to \n ? That should be easy...
Or do you mean that once I use <\around> then copying code snipplets
is a bit of a pain, because I can only select the whole <\around>, not
parts of it? I'll have to start using it to see how much I hate it.

Yes. I wonder what I should use. It seems in math nothing is displayed....
Another option I thought about was that if you delete a bracket, then
the <\around| ( | "body" | ) > would be replaced by just "body".

But for now, I think I can easily get a workable version. Cool!
