2.2 Buttons and other controls on the screen
When you are using Zenec navigation, you usually tap buttons on the touch screen.
You only need to confirm selections or changes if the application needs to restart, it needs to
perform a major reconfiguration, or you are about to lose some of your data or settings.
Otherwise, Zenec navigation saves your selections and applies the new settings without
confirmation as soon as you use the controls.
