serious, since the minus symbol is pretty common.
Probably something with your keyboard settings.
2. Currently is there any solutions for commutative diagrams?Nothing really great yet. Two imperfect solutions exist:
1) For simple diagrams, you may simply use a table environment and
the standard arrows in TeXmacs.
2) If you need lots of complex diagrams, then you may consider
drawing a picture for each diagram. Textual fields come with
special handles for attaching arrows.
In the future, solution 2 will probably be developed much further.
