Select Auto-Save from the File menu to display this window.
When there is no ‚àö mark next to Auto-Save in the File menu and you select Auto-Save in the File menu, you will be asked to confirm that you want to turn on Auto-Save for this document. Click on OK to activate Auto-Save. The time duration is set in the Preferences. Selecting Auto-Save again turns off Auto-Save and removes the ‚àö mark.
In this example, the file “myTime” is saved to disk every 5 minutes. This is helpful in the event your Mac ever crashes (not your Mac!).
See the chapter on Preferences for more information.
