;;; Commentary:
-;; Loading this package defines two ways of entering the ISO Latin 1 characters
-;; with codes above 127.
+;; Loading this package defines three ways of entering the non-ASCII
+;; printable characters with codes above 127: the prefix C-x 8, or the
+;; Alt key, or a dead accent key. For example, you can enter uppercase
+;; A-umlaut as `C-x 8 " A' or `Alt-" A' (if you have an Alt key) or
+;; `umlaut A' (if you have an umlaut/diaeresis key).
-;; One way is to type C-x 8 followed by a special chaacter sequence.
-;; For example, C-x 8 " A enters an upper-case A-umlaut.
-
-;; The other way is to type the same special sequence
-;; but hold down Alt for the first character in it.
+;; C-x 8 is set up to autoload this package,
+;; but Alt keys and dead accent keys are only defined
+;; once you have loaded the package. It is nontrivial
+;; to make all of the Alt keys autoload, and it is not clear
+;; that the dead accent keys SHOULD autoload this package.
;;; Code:
+;;; Provide some binding for startup:
+;;;###autoload (or key-translation-map (setq key-translation-map (make-sparse-keymap)))
+;;;###autoload (define-key key-translation-map "\C-x8" 'iso-transl-ctl-x-8-map)
+;;;###autoload (autoload 'iso-transl-ctl-x-8-map "iso-transl" "Keymap for C-x 8 prefix." t 'keymap)
