2.3 Buttons and other controls on the screen
When you are using the software, 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, the
software saves your selections and applies the new settings without confirmation as soon as you use
the controls.
