If you are willing to hack a bit, then look at the routine close-quotes?
in progs/utils/edit/auto-close.scm. The verbatim like stuff could be dealt
with using contextual overloading, as explained in

        Help -> Scheme extensions -> Overview of the scheme extension language
        Section 5

In the other sections, you will find most other things you might want
to know in order to hack.

I agree that more attention should be paid to the keyboard in verbatim mode
(really prog mode, I think). Currently, there is still some confusion about
different verbatim like tags, prog mode, verbatim language, etc.
After all, maybe I should fix all that, when I will have time...

Best wishes, Joris
