;;; Commentary:
|
||
|
||
;; 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).
|
||
|
||
;; 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.
|
||
|
||
;; This package supports all characters defined by ISO 8859-1, along
|
||
;; with a few other ISO 10646 characters commonly used in English and
|
||
;; basic math.
|
||
|
||
;;; Code:
|
||
|
||
;;; Provide some binding for startup:
|
||
;;;###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)
