Having forgotten the command to make text bold in math mode I naively tried
$\bold{bold var goes here} these maths symbols are not bold$
and it worked! I became immediately suspicious as I know LaTeX font commands are never that `nice'. I haven't been able to find anything about this command online. By experimentation I found that amsfonts or amssymb are responsible.
My main question is to please explain where this command came from: where in which package. The additional question is how can one find out where any given command comes from using just his computer (if not possible, then the easiest way with the internet)?
\boldmath
for steady bold font and\bm
for local changes (or\mathbf{}
). There's an outdated command also, but I can't never remember which one it is.\bold{...}
works with AMS-TeX, not with LaTeX.\boldmath
must be stipulated outside of math mode.
