Keyboard bindings in EMACS

Emacs offers several ways of adding keybindings for macros:

• global keybindings will be active regardless of the mode of emacs
• keybindings which are only active in a certain mode.

For quick hacks, such as repeatingly use a macro that you create with the macro recorder (which is a simple keyboard repeater), it is easiest to define a global keybinding without saving it in .emacs, that way the keybinding will disappear when you exit emacs. (In that case, name the macro and the invoke global-set-key using M-x, and follow the instructions).

To add a keybinding for a macro provided by a mode, you use the function local-set-key in the hook for the mode.

I want to bind two functions from ess-mode like this:

To achive this, I put the following in .emacs.

;; keybindings for ess
(defun my-ess-hook ()
  "Add my keybindings to ESS mode."
  (local-set-key (kbd "<f5>") 'ess-eval-chunk)
  (local-set-key (kbd "<f6>") 'ess-noweb-next-chunk)
)
(add-hook 'ess-mode-hook 'my-ess-hook)
