Setting up Switch Scanning
As an alternative to directly selecting each button on the screen, the
application offers single-switch scanning and two-switch scanning.
You can choose to have scanning activate automatically, or you can
choose to either hold the switch or step to each location. With Auto
Scan off, a switch activation is required to move the scan through each
button, one at a time.
To access the options for customizing a scanning technique, choose
