Great. I don't think you're misunderstanding me, but just in case,
let me clarify one thing: I'm not trying to persuade everyone to
change to mathbf. The default situation in Sage is to use \mathbf (as
William has explained), and I'm trying to codify this, and also
provide a way to globally change it for people who object to it.

When you build the documentation, you are running Python, not Sage (as
far as I can tell), so I don't know how to pass the appropriate
customizations. A command-line switch would probably do it, but I'm
afraid that it might be a bit clunky.

Maybe a setting in an init.sage file? How do you use that file? Can
you just put 'latex_customize.use_blackboard_bold(True)' in it?

I intend it to be used only for those circumstances where reasonable
people might want to switch from one choice to the other, so I tried
to change \mathbf to \Bold only for ZZ, RR, QQ, CC, and perhaps for P
(projective space). I certainly left other uses of \mathbf{blah} and
\mathbb{blah} in the code. I probably missed some cases, and I
probably changed a few I shouldn't have, but do my intentions sound
right? (Answering you literally, some people would suggest that
blackboard fonts would always be inappropriate :)
