In some instances it may be useful to edit a pre-existing overlay. For example, you might want to delete some keys that a student could find distracting, reposition some keys to make them easier to press, or change the color of a key to make it easier to see. Overlay Maker 3 allows you to edit an overlay that is already attached to a document, or to edit an overlay that has not yet been attached to a document (perhaps one that another teacher has already designed).
How do I edit an attached overlay?
When I use Make Overlay, where is the attached overlay saved?
