scrolled when the scroll arrows are tapped and which view is currently

Also keep in mind when designing your application that future Newton
devices may have larger or smaller screens than current Newton devices. To
work with different screen sizes, a Newton application must check the screen
size and make adjustments as needed to the size and location of the things it
displays so that everything fits. If you want your application to work in
either of the two display orientations available on an Apple MessagePad 120,
your application needs to be able to adjust the position and configuration
of everything it displays for regular or sideways orientation of the display.

keyboard adjust their size, position, and layout when a user rotates
the display.
