2.2 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.
