Hi John,
Within Sage, you can get the appropriate command with
sage: from sage.misc.latex_macros import sage_configurable_latex_macros
sage: sage_configurable_latex_macros
['\\newcommand{\\Bold}[1]{\\mathbf{#1}}']
sage: print(sage_configurable_latex_macros[0])
\newcommand{\Bold}[1]{\mathbf{#1}}
I'm not sure how SageTeX is supposed to handle this, and I'm surprised that
it hasn't come up before. The use of \Bold{...} in Sage dates back to 2009:
see sage/misc/latex_macros.py.
