Automatic save is defined as a personal preference, independently for each user, and independently for type of content and for application..
By default, the auto-save is not enabled.
In Ted4 and Fred4
There are two auto-saves: one for pages (Pages main tab, Edit > Preferences), and one for articles (Articles main tab, Edit > Preferences, or during text editing on the Pages main tab, Edit > Preferences).
The dialog box titles are Fred Preferences (for pages), and Ted4 preferences (for text editing).
For the instructions, see Enable and configure auto-save of pages and Enable and configure the auto-save of text.
