Shortly after writing this message I noticed that the fact of
having a toplevel function is independant of my problem, so I
now restate it in a simpler form.
(defobfun (make-error *fred-window*) ()
(error "An error occured."))
(def-fred-command (:control #\enter) make-error)
;; If you do a (:control #\enter) during the (read)...
