double-mode

double-mode is an interactive autoloaded compiled Lisp function in `double.el'.


(double-mode &optional ARG)

Toggle special insertion on double keypresses (Double mode).
With a prefix argument ARG, enable Double mode if ARG is
positive, and disable it otherwise. If called from Lisp, enable
the mode if ARG is omitted or nil.

When Double mode is enabled, some keys will insert different
strings when pressed twice. See `double-map' for details.
