This works of course, but I don't want to write something like
(minimal example ;)
$$\hbox{\switchtobodyfont[iwona-heavy]$B$}=\hbox{\switchtobodyfont[iwona-heavy]$\nabla$}\times\hbox{\switchtobodyfont[iwona-heavy]$A$}$$
even if I define my own shortcut to it.
(\displaystyle, \textstyle, ... spacing, readability unless I can
redefine \bf and so on ...)

That's what I'm looking for, but I can't find that magical piece of
code in huge typescripts definitions.

No, I really don't need that complex solution. My needs are already
covered by the "MyWay" with bold math and in cm bold math works as
well. It's just that I can't read the manual / cannot repeat the
process and get rid of cm fonts.

Thanks a lot,
