Setting the Scanning Style
You can choose to have the system automatically scan or to step to each location. With step-scanning, a
switch must be pressed to move the scan to each button, one at a time. With auto-scanning, a switch
must be pressed to start the scan and the system will continue to scan until the switch is pressed again.
To set the scanning style, choose Settings > General > Accessibility > Switch Control > Scanning Style.
Three scanning styles are available: Auto Scanning, Manual Scanning, and Single Switch Step Scanning.
Note:
Long Press is not currently available within the TouchChat app.
