really weird in
cases where letters are longer, or when we have combinations of them)
b) vectors should be harpoons (not arrows) according to our conventions.
My old \overrightharpoonup definitions had two other problems:
c) scalability/interfering with style change: you solved exactly that
one

Hello,
What exactly is the ConTeXt alternative to LaTeX's \mathbf (switch to
bold or bold italic math fonts)?
(Btw: is it better to use bold or bold italic for typesetting vectors?
We use overrightharpoonup, so I don't know what an international
standard says.)
I understand the main commands
