- the right function key (labeled ③ in the diagram above) can often be used to go forward to the next page resp. measurement, pressing it has the same effect as touching (clicking) the graphical "next" button displayed on the touch screen.
- the left function key (labeled ⑩ in the diagram above) can often be used to go back to the previous page, pressing it has the same effect as touching (clicking) the graphical "back" button displayed on the touch screen.
The "Esc" button (labeled ⑨ in the diagram above) often has the same effect, but Android's "back" / "back out" semantics furthermore navigates across application layers and even applications.
