  27 ;;; Commentary:
  28
  29 ;; Function `iso-accents-mode' activates a minor mode in which
  30 ;; typewriter "dead keys" are emulated.  The purpose of this emulation
  31 ;; is to provide a simple means for inserting accented characters
  32 ;; according to the ISO-8859-1...3 character sets.
  33 ;;
  34 ;; In `iso-accents-mode', pseudo accent characters are used to
  35 ;; introduce accented keys.  The pseudo-accent characters are:
  36 ;;
  37 ;;   '  (minute)    -> actue accent
  38 ;;   `  (backtick)  -> grave accent
  39 ;;   "  (second)    -> diaeresis
  40 ;;   ^  (caret)     -> circumflex
  41 ;;   ~  (tilde)     -> tilde over the character
  42 ;;   /  (slash)     -> slash through the character.
  43 ;;                     Also:  /A is A-with-ring and /E is AE ligature.
  44 ;; These two are enabled only if you set iso-accents-enable
  45 ;; to include them:
  46 ;;   .  (period)    -> dot over the character (some languages only)
  47 ;;   ,  (cedilla)   -> cedilla under the character (some languages only)
  48 ;;
  49 ;; The action taken depends on the key that follows the pseudo accent.
  50 ;; In general:
  51 ;;
  52 ;;   pseudo-accent + appropriate letter -> accented letter
  53 ;;   pseudo-accent + space -> pseudo-accent (except comma and period)
  54 ;;   pseudo-accent + pseudo-accent -> accent (if available)
  55 ;;   pseudo-accent + other -> pseudo-accent + other
  56 ;;
  57 ;; If the pseudo-accent is followed by anything else than a
  58 ;; self-insert-command, the dead-key code is terminated, the
  59 ;; pseudo-accent inserted 'as is' and the bell is rung to signal this.
  60 ;;
  61 ;; Function `iso-accents-mode' can be used to enable the iso accents
  62 ;; minor mode, or disable it.
  63
  64 ;; If you want only some of these characters to serve as accents,
  65 ;; add a language to `iso-languages' which specifies the accent characters
  66 ;; that you want, then select the language with `iso-accents-customize'.
