Dear Alvaro,

Thanks for your feedback.

I just fixed this problem.

Probably fixed as well.

I only observe this in the Qt version and already reported
a similar bug to Massimiliano.

The first time that you hit this submenu, TeXmacs may indeed freeze
for a few seconds. Afterwards, the locations of fonts are cached.
I will think about a more satisfactory solution when reorganizing
the TeXmacs font management.

That "bug" was already present before.
It depends on whether documentation should open fast or not.

Yes, and similarly for '+', '-', etc.
I plan to work on this issue.

I prefer to be systematic: we also do not insert space after, say, 'sin'.

Yes, that makes it easier to visually distinguish these special constants,
which is also a convention used by several publishers, including Elsevier.

Most of the documentation is contextual, but there are a few exceptions.

What did you type in order to enter, say (a,b] ?

Where did you try to put the cursor?

Best, --Joris
