+;; In `iso-accents-mode', pseudo accent characters are used to

;;
;; ' (minute) -> grave accent
;; ` (backtick) -> acute accent
;; ^ (caret) -> circumflex
;; ~ (tilde) -> tilde over the character
;; / (slash) -> slash through the character.
-;; Also: /A is A-with-ring and /E is AE ligature.
+;; Also: /A is A-with-ring and /E is AE ligature.
+;; These two are enabled only if you set iso-accents-enable
+;; to include them:
+;; . (period) -> dot over the character (some languages only)
+;; , (cedilla) -> cedilla under the character (some languages only)
;;
;; The action taken depends on the key that follows the pseudo accent.
;; In general:
;;
;; pseudo-accent + appropriate letter -> accented letter
-;; pseudo-accent + space -> pseudo-accent
+;; pseudo-accent + space -> pseudo-accent (except comma and period)
;; pseudo-accent + pseudo-accent -> accent (if available)
;; pseudo-accent + other -> pseudo-accent + other
;;
;;
;; Function `iso-accents-mode' can be used to enable the iso accents
;; minor mode, or disable it.
+
+;; If you want only some of these characters to serve as accents,
+;; add a language to `iso-languages' which specifies the accent characters
+;; that you want, then select the language with `iso-accents-customize'.
