The Active Category is highlighted as is the active Selection. Note: The areas that can be revised are in a different background color. Make the changes you want to make in these areas and click with your mouse on a Selection inside the Search Selections area to make the changes permanent. No changes are permanent until you have clicked on a Selection in the Search Selections area. Once the Revision has been made permanent you cannot reverse and go back to the way it was. You can do as many Revisions as you want to a recipe though. So, you can Revise it back if you want.
