Edit regions in separate buffers, like org-edit-src-code but for arbitrary regions.

The package is available in MELPA.

If you have MELPA in package-archives, use

M-x package-install RET edit-indirect RET

If you don't, open edit-indirect.el in Emacs and call package-install-from-buffer.

To start editing, run:

M-x edit-indirect-region

• C-c ' or C-c C-c to commit the changes

• C-c C-k to abort

• edit-indirect-guess-mode-function

the default value is #'edit-indirect-default-guess-mode, but if language-detection is available, you can also use #'edit-indirect-language-detection-guess-mode, which detects mode automatically by region contents.
