Hi,
I needed to use \boldsymbol recently, and studied the different
solutions that have been posted on the mailing list. Using a \hbox
wrapper seems to be the easiest way, but none of the definitions using
\hbox took care of spacing around the symbols. Since ConTeXt now has
equivalents of amsmath's \binrel@ and \binrel@@ commands, here is an
improved definition of \boldsymbol.
\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [modern]
[encoding=texnansi]
\unprotect
\def\boldsymbol#1%
{\preparebinrel{#1}%
\currentbinrel
{\mathchoice
{\hbox{\switchtoformulabodyfont [boldmath]$\m@th#1$}}
{\hbox{\switchtoformulabodyfont [boldmath]$\m@th#1$}}
{\hbox{\switchtoformulabodyfont [boldmath,script]$\m@th#1$}}
{\hbox{\switchtoformulabodyfont[boldmath,scriptscript]$\m@th#1$}}}}
\protect
\starttext
$a \times b$ $a \boldsymbol{\times} b$
\stoptext
This is equivalent to \boldsymbol of amsbsy.sty. I have added this to
the wiki,
Aditya
