Common customizations
Outlining
For Org-style outlining, add the following customizations.
;; Turn on outline minor mode
(add-hook 'emacs-lisp-mode-hook 'outline-minor-mode)
;; Add key bindings for Org-style outline cycling
(add-hook 'outline-minor-mode-hook
(lambda ()
(define-key outline-minor-mode-map [(control tab)] 'org-cycle)
(define-key outline-minor-mode-map [(shift tab)] 'org-global-cycle)))
Now visit any elisp file (say M-x find-library RET outline) and keep pressing [S-TAB] and see what happens. Experiment similarly with [C-TAB].
Indentation
Add following customization, so that you don't have to indent deliberately. See reindent-then-newline-and-indent.
(add-hook 'emacs-lisp-mode-hook
(lambda nil
(local-set-key [(return)] 'reindent-then-newline-and-indent)))
