kirigami

The kirigami package offers a unified interface for opening and
closing folds across a diverse set of major and minor modes in Emacs,
including `treesit-fold-mode', `outline-mode', `outline-minor-mode',
`outline-indent-minor-mode', `org-mode', `markdown-mode', `gfm-mode',
`outli-mode', `embark-collect-mode', `vdiff-mode', `vdiff-3way-mode',
`hs-minor-mode' (hideshow), `hide-ifdef-mode', `vimish-fold-mode',
`TeX-fold-mode' (AUCTeX), `fold-this-mode', `origami-mode', `yafolding-mode',
`folding-mode', `ts-fold-mode', `ibuffer-mode', and `profiler-report-mode'.

With Kirigami, folding key bindings only need to be configured once. After
that, the same keys work consistently across all supported major and minor
modes, providing a unified and predictable folding experience. The available
commands include:

- `kirigami-open-fold': Open the fold at point.
- `kirigami-open-fold-rec': Open the fold at point recursively.
- `kirigami-close-fold': Close the fold at point.
- `kirigami-open-folds': Open all folds in the buffer.
- `kirigami-close-folds': Close all folds in the buffer.
- `kirigami-toggle-fold': Toggle the fold at point.

(In addition to unified interface, the kirigami package enhances folding
behavior in outline-mode, outline-minor-mode, markdown-mode, and
org-mode. It ensures that deep folds open reliably and allows folds to be
closed even when the cursor is positioned inside the content.)
