3.2 Screen buttons and controls
The primary input channel of V7 Navigation is the touch screen. If you read on, you
will realize that most parts of the screen are not only used to display information but
also to initiate functions by tapping. Below you will find a list of the most frequently
used controls in the program.
3.2.1 Direct selectors
Some of the settings can be chosen from a short list of possible values. If the values
can be described graphically, all values are available on the screen.
Tap one of the icons to set/change the value.
3.2.2 List selectors
When the values in the list need to be named, only the current value is shown
(sometimes together with a short description) in a horizontal stripe with arrows at
both ends.
The arrows are buttons. Tap to move left in the list or tap to move right.
You need not confirm your selection. As soon as you leave the screen, the selected
value becomes effective.

value.
