If you selected the option Add key retrieval on the previous screen, you can select the (optional) additional Screen Fields that ITP has to display in a Key Selection screen. When you add additional Screen Fields, the end user will be able to make an easier selection in many cases.

ITP will always display the Formal Parameters that you specified for an Entry.

The order in which the selected Fields appear in the Wizard, is not related to the order in which they appear in the Entry Definition. You will have to change the Entry Definition manually to specify an order.
