To provide control over how your data entry screen is entered (not applicable for Inquiry Only Task Screens).
If left as the default (DEFAULT), the code generator navigation engine will use the TaskScreen's Screen attribute (if set) to determine, based on the Screen location in the source recording, which enter key to use.
If the Screen attribute is not set, the enter key used will be based on the first transition found between the TaskScreen for this property and the first OKScreen in the list (or the next TaskScreen defined in the Task)
