key-combo.el

key-combo is an Emacs package that provides "cycling" key-binding. Multiple commands are executed sequentially with a repeated keypress of a single key. Multi-key cords can also be bound to a sequences of characters or commands in order to create complex "smart operator" effects.

Instalation

This package is available from MELPA. Alternatively you can place key-combo.el into your emacs path and add (require 'key-combo) to your init file.

Activation

Activate key-combo-mode localy in a mode hook with:

(key-combo-mode 1)

or globally with

(global-key-combo-mode t)

Configuration

Define cycling key combos globally with key-combo-define-global function:

(key-combo-define-global "=" '(" = " " == " " === " )) ;cycling
(key-combo-define-global "=>" " => ")
(key-combo-define-global "C-a" `(back-to-indentation move-beginning-of-line
                                 beginning-of-buffer key-combo-return))
(key-combo-define-global "C-e" '(move-end-of-line end-of-buffer key-combo-return))

or for each modes separately:

(key-combo-define emacs-lisp-mode-map "="  '("= " "eq " "equal "))

There is also key-combo-define-local that should be used inside mode hooks.

To facilitate quick declaration of cord, key-combo.el provides key-combo-define-hook which is used to setup same hook for a list of modes. Here is a simple example for emacs-lisp:

(defvar my-lisp-mode-hooks
  '(lisp-mode-hook
    emacs-lisp-mode-hook
    lisp-interaction-mode-hook
    inferior-gauche-mode-hook
    scheme-mode-hook))

(defvar my-key-combos-for-lisp
  '(("."  . ("." " . "))
    (","  . (key-combo-execute-original))
    (",@" . " ,@")
    (";=" . ";=> ")
    ("="  . ("= " "eq " "equal "))
    (">=" . ">= ")))

(key-combo-define-hook my-lisp-mode-hooks ; hooks
                       'my-key-combo-lisp-hook ; function name
                       my-key-combos-for-lisp)

Default Configuration

To load a range of default configurations for lisp, C, C++, js, org etc modes, use:

(key-combo-load-default)
