When a unique match is found, the full item is displayed in the edit control. The automatically completed portion of the item is highlighted. You can replace the highlighted portion of the item by typing over it, or you can delete the highlighted portion of the item using the DELETE key or the BACKSPACE key. The default value is FALSE.
