[OS X TeX] Verbatim mode question...

Ouch; that would be technically a *very* difficult thing to do.

Do you really need verbatim ?
Or is it just the \texttt mono-spaced font style that you need ?

As a general rule, true verbatim (as with \verb+...+) cannot work
in the argument of a LaTeX command.
This is because \verb needs to change the interpretation of
special characters *before* they are read by TeX.

Once the argument has been read, the interpretation has been frozen,
so to speak, as that normally used in (La)TeX documents.
(e.g. a $ means a math-shift operation, not a dollar-symbol).
It can no longer be changed.

Most special characters can be obtained by simple macros:
 \$ \@ \_ \% \&   ( \^{} \~{} are not quite right )

There is some TeX trickery that can be used in some places,
but being within  \caption  adds an extra degree of difficulty,
as it's argument is used in 2 places:

  1. as the caption to a figure, when placed
and
  2. within the List of Figures page.

To make trickery work correctly in both places would be quite hard.

It will involve writing macros, and using those within the captions.
\DeclareRobustCommand , or similar ideas, will play some role.

I'd need to see exactly what you are trying to do, to be able
to work out the best way to handle it.


Hope this helps,
