Done.

Luckily that's already how it works; I just chose to not document the
fallback (done that now).  If the macro is not available, then @code{}
is used instead.

I tried but could not get it to work that way.  Whatever I tried
ox-texinfo insisted on breaking it by adding quotes.

I didn't go as far as to try injecting export-snippet elements into the
tree because without using org-macro-replace-all it seemed painful to do
that.  But on second thought...

Would it be okay to represent e.g. "C-c SPC" as:

   (export-snippet
    (:back-end "texinfo" :value "@kbd{C-c @key{SPC}}" :post-blank 0 :parent #2))

instead of the more painful to construct:

   (export-snippet
    (:back-end "texinfo" :value "@kbd{" :begin 317 :end 334 :post-blank 0 :parent #2))
   #("C-c " 0 4
     (:parent #2))
   (export-snippet
    (:back-end "texinfo" :value "@key{" :begin 338 :end 355 :post-blank 0 :parent #2))
   #("SPC" 0 3
     (:parent #2))
   (export-snippet
    (:back-end "texinfo" :value "}" :begin 358 :end 371 :post-blank 0 :parent #2))
   (export-snippet
    (:back-end "texinfo" :value "}" :begin 371 :end 384 :post-blank 0 :parent #2))

Err, that's what I would usually do.  Not sure why not here.

Done.

Done.

(Not a fan personally.  IMO rx is less readable than a plain old
regexp, though that's probably just because I never took the time
to retrain myself.)

I think that is one of the things I tried that ox-texinfo insisted on
quoting anyway.  I might misremember, so I will have another look.
Above I suggested using an `export-snippet' element (instead of `raw');
to me that seems appropriate too.

     Cheers,
