Aloha Seb,

Do you mean the variable org-export-latex-use-verb?  I haven't looked  
into its history in the git repo.  Currently it defaults to nil, so  
\verb is not used and \texttt is used in its place.

Carsten has a patch on the list today that changes the default to t,  
which means that what you see in the alist is pretty much what you  
get.  For reasons having to do with typesetting code snippets (that I  
don't fully understand), Carsten protects special characters in  
\texttt.  This means that the alist doesn't contain a markup character  
that yields straight \texttt, though it should be straightforward to  
add one.

I hope this helps.  In any event, it represents the limit of my  
understanding of what goes on in org-latex.el, which I freely admit  
falls far short of full comprehension.

All the best,
Tom
