;;; Commentary:
;; This provides `autoarg-mode', a global minor mode meant to emulate
;; a facility reported from Twenex Emacs whereby digit keys supplied
;; prefix args rather than self inserting, with a digit sequence
;; terminated by space acting to insert the digits.
;; The bindings of DIGIT and C-DIGIT are swapped and a command bound
;; to SPC deals with a numeric prefix arg or acts normally without
;; such an arg. (In the absence of a suitable terminal, you'd
;; probably want to swap DIGIT and M-DIGIT.) See the mode doc.
;; You probably don't really want to use this.
;; Also provides `autoarg-kp-mode' which is similar, but leaves the
;; digit keys alone and redefines the `keypad' keys, `kp-1' &c as
;; digit arguments. (Use `NumLock' if necessary to generate kp-N.)
;; You're more likely to want to use this.

\\<autoarg-mode-map>
In Autoarg mode digits are bound to `digit-argument' -- i.e. they
supply prefix arguments as C-DIGIT and M-DIGIT normally do -- and
C-DIGIT inserts DIGIT. \\[autoarg-terminate] terminates the prefix sequence
and inserts the digits of the autoarg sequence into the buffer.
Without a numeric prefix arg the normal binding of \\[autoarg-terminate] is
invoked, i.e. what it would be with Autoarg mode off.
For example:
`6 9 \\[autoarg-terminate]' inserts `69' into the buffer, as does `C-6 C-9'.
`6 9 a' inserts 69 `a's into the buffer.
`6 9 \\[autoarg-terminate] \\[autoarg-terminate]' inserts `69' into the buffer and
then invokes the normal binding of \\[autoarg-terminate].
`C-u \\[autoarg-terminate]' invokes the normal binding of \\[autoarg-terminate] four times.
