;;; You may also want to bind hide-body, hide-subtree, show-substree, ;;; show-all, show-children, ... to some keys easy folding and unfolding (add-hook 'ruby-mode-hook '(lambda () (outline-minor-mode) (setq outline-regexp " *\\(def \\|class\\|module\\)"))) ; Outline-minor-mode key map (global-set-key [M-left] 'hide-body) (global-set-key [M-right] 'show-all) (global-set-key [M-up] 'hide-entry) (global-set-key [M-down] 'show-entry)
Then use M plus arrow keys to fold and open method/class/module blocks.
M-left # will fold all. M-right # will open all. M-down # will open current block. M-up # will close current block.
