For a character mode host, sets the default key to send for the last field on a screen. The default value is [home] which sends the active definition for a home key after the text is entered for the field.
To stop any keys from being sent after the text of the last field, set this value to null.
Note that if the last field on the screen has the NextFieldKey property set to Custom Keystrokes, the NextFieldCustomKeys for that field will be used instead of this setting.
