→An Alternate Definition: An improved definition
An alternate way to define <cmd>boldsymbol</cmd> is
<texcodecontext source="yes">\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]$\m@th#1$}}}}</texcode>\protect
$\grad \eta = e^{\vec k \cdot \vec x} \unitvec{n}$
</context>
The <cmd>preparebinrel</cmd> and <cmd>currentbinrel</cmd> ensure that the correct spacing is used around the symbol.
This is slightly more efficient than the first version.
