You can use

,----[ C-h f hs-minor-mode RET ]
| hs-minor-mode is an interactive compiled Lisp function in `hideshow.el'.
| (hs-minor-mode &optional ARG)
| 
| Toggle hideshow minor mode.
| With ARG, turn hideshow minor mode on if ARG is positive, off otherwise.
| When hideshow minor mode is on, the menu bar is augmented with hideshow
| commands and the hideshow commands are enabled.
| The value '(hs . t) is added to `buffer-invisibility-spec'.
| 
| The main commands are: `hs-hide-all', `hs-show-all', `hs-hide-block',
| `hs-show-block', `hs-hide-level' and `hs-toggle-hiding'.  There is also
| `hs-hide-initial-comment-block' and `hs-mouse-toggle-hiding'.
| 
| Turning hideshow minor mode off reverts the menu bar and the
| variables to default values and disables the hideshow commands.
| 
| Lastly, the normal hook `hs-minor-mode-hook' is run using `run-hooks'.
| 
| Key bindings:
| key             binding
| ---             -------
| 
| C-c             Prefix Command
| <S-mouse-2>     hs-mouse-toggle-hiding
| 
| C-c @           Prefix Command
| 
| C-c @ C-c       hs-toggle-hiding
| C-c @ C-h       hs-hide-block
| C-c @ C-l       hs-hide-level
| C-c @ C-s       hs-show-block
| C-c @ ESC       Prefix Command
| 
| C-c @ C-M-h     hs-hide-all
| C-c @ C-M-s     hs-show-all
`----

It works for a lot of languages, not only lisp.
