Hello, thanks for the example. I can see that: - In another font(s) (at least in cambria in your example) bold Greek chars are OK. - \bf in math mode causes chars to become "vertical", i.e. when I want to get slanted chars, I have to call \it or \sl or \bi explicitly. OK, I thought that the "slantedness" is kept by default when switching to bold in math mode, but no problem to switch to slanted/italics font manually. - But I still have no idea how to "restore" Greek chars when using the *default* bold math font (i.e. when not using \setupbodyfont[<another-font>]. Or do I have to \setup???font[???] explicitly when I want to use Greek bold chars as well?
IMHO (I'm not expert in context) this depends on used fonts. See for example follwoing: <example file="ex1.tex"> \setupbodyfont[cambria]
\starttext This is a test. $a=\alpha$ $\bf a=\alpha$ $\bi a=\alpha$ \stoptext </example>
BTW, I not sure if I use "correct" way to switch fonts in math mode (in LaTeX commands to switch fonts are different in text and math mode, and I have big LaTex background, so for me this way is unusual :).
NB: I used to work with LaTeX as well - I'm still time-to-time solving "basic things" (like that above) in ConTeXt. Best regards, Lukas
P.S. My example works with mkiv but not with mkii. The last uses "default" fonts that don't have bold variant for greek letters (I could be wrong here, for LaTeX I have to redefine commands for greek letters because there is appropriate font but greek letters are defined in a way so nobody could use bold variant by default).
