Documentation

Non-nil if Auto-Compression mode is enabled.

See the auto-compression-mode(var)/auto-compression-mode(fun) command for a description of this minor mode. Setting this variable directly does not take effect; either customize it (see the info node (emacs)Easy Customization) or call the function auto-compression-mode(var)/auto-compression-mode(fun).

This variable was added, or its default value changed, in Emacs 22.1.

Probably introduced at or before Emacs version 19.30.
