Hello Noam,
Below is a more appropriate answer to your question.
"Text typed into the Atto editor is automatically saved if you leave the page." See Atto editor / Autosave ↗ for details.
"The default of 60 seconds may be changed by the administrator in Site administration>Plugins>Text editors>Atto HTML editor>Atto toolbar settings." The "Autosave frequency" setting is at the very bottom of this page. If you set it to say 1 second, the text in the editor will be saved almost continuously.
