The user can either click on the option to save and keep working which is an option on the green save button which you can enable on the form properties, or else the user could push a button to save and keep working.
But I don't think it's possible to trigger an auto save based on the user entering data in certain fields.
Feel free to post back if you need help with a button which will save and continue editing.
