One thing first, iint does not seem defined as a symbol. Maybe you
actually want to go the whole way to creating a new big operator, but
I do not know how to do that.

Maybe one should be able to do
   ("math:symbol I var" (make-big-operator "iint") (make-big-operator "iint"))
but this does not seem easily possible. The problem seems to lie
somewher in the editor core.

make-big-operator does
(lambda (x) (insert-object `(big ,x)))

Which involve some quite complicated code. When texmacs goes back to
the main loop it seems to disable the shortcut input mode.

The important thing is that there is no problem when inserting atoms
(simple symbols), and I see no reason why that should not be possible
for more complicated expressions too.
