LaTeX: \Ob
Introduced a macro
\def\Ob{\mathop{\rm Ob}\nolimits}
and replaced any occurence of \text{Ob}( with \Ob(. There are
still some occurences of \text{Ob} but these are sets, not the
operator that takes the set of objects of a category.

Embedding abelian categories
It is easy to embed any abelian category into the category of
abelian sheaves on a site having enough points. Of course this
requires you to understand about sheaves, points of sites, etc
but it seems that this is going to be true for most algebraic
geometers who learn about etale cohomology at some point. From
this one can then deduce the Freyd-Mitchell embedding theorem.
