Use connections to connect the screens with actions in the Flow Design.
Connection actions describe the navigation direction the screen should
go after the user performs an action, cancels an action, or uses a control. Alert actions use actions defined in the Flow Design.
Note: You can use only one connection of each type from a given source
screen, except for the Go To connection type. You can have as many Go To
connection types as you want to on a source screen, but there cannot be more
than one Go To connection to the same target screen.
