org-edit-src-turn-on-auto-save

org-edit-src-turn-on-auto-save is a variable defined in `org-src.el'.
Its value is

nil

Documentation:
Non-nil means turn `auto-save-mode' on when editing a source block.
This will save the content of the source code editing buffer into
a newly created file, not the base buffer for this source block.

If you want to regularly save the base buffer instead of the source
code editing buffer, see `org-edit-src-auto-save-idle-delay' instead.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 24.4 of Emacs.
