Example: I understand that .B and \fB do the

I don't know if they do *exactly* the same thing.
\fB says switch to the "physical" font named 'B' (as far as troff is concerned).
.B says I want to print in a "bold" font.
These are not the same thing. Using .B lets the implementation select an
appropriate font for the current output device, or for the current context.
E.g., some systems print .B text using a fixed-width font when driving a
typesetter device. In that case, '.B foo' and '\fBfoo\fP' don't generate the
same output.
