You can attach an LOV to one or more text items in a form. When the end user or the application navigates to a text item to which an LOV is attached, Oracle Forms displays the LOV List lamp on the status line to indicate that an LOV is available. End users can invoke the LOV by pressing [List of Values].
Or, if you set the LOV's Automatic Display property to Yes, Oracle Forms displays the LOV automatically when the end user navigates to the text item.
