-;;; Commentary:
-
-;; Things we cannot emulate in Lisp:
-;; It is not possible to emulate current-mouse-event as a variable,
-;; though it is not hard to obtain the data from (this-command-keys).
-
-;; We do not have a variable unread-command-event;
-;; instead, we have the more general unread-command-events.
-
-;; Our read-key-sequence and read-char are not precisely
-;; compatible with those in Lucid Emacs, but they should work ok.
