# [NTG-context] boldsymbol workaround

Hi all,

I've just found a little workaround for using boldsymbols. It works even with the nath module. It's probably not the best way of doing it, but since it does the trick for me, I guess it might useful to other ConTeXters.

Here it is:

\define[1]\boldsymbol{{\hbox{\formula{\bfm #1}}}}

I also have to:

\definebodyfont
[17.3pt,14.4pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt,4pt]
[mm]
[mrbf=cmbx10 sa 1,
exbf=cmex10  sa 1,
mibf=cmmib10 sa 1,
sybf=cmbsy10 sa 1,
mabf=msam10  sa 1]

\setupformulae[method=bold]

Then, I may define very handy commands like

\define\grad{\boldsymbol{\nabla}}
\define[1]\vec{\boldsymbol{#1}}
\define[1]\unitvec{\hat{\vec{#1}}}

and formulas like this typeset perfectly:

$\grad h = a \unitvec{n}$
