3.2 Keyboard Summary

Accessibility aid

This feature allows a user with limited motor skills to use modifier key combinations in a sequential manner rather than in

a simultaneous manner. All modifier key combinations are supported. There are two operation states—Latch and Lock. The Latch state affects only the next key pressed. When in the Lock state, all keys pressed are affected by the modifier until you press the same modifier key again or press any other modifier key twice. A small icon, indicating the state, is displayed on the Keyboard Indicator Line

or the Status Line.

To enable: Press any modifier key five times.

Latch state: Press any modifier key once.

Lock state: Press any modifier key twice.

To disable: Press and hold a modifier key while you press another key.

Review previous lines

In Set-Up or through software, you can allocate the pages that are assigned to each session, up to a total of nine pages. When Review previous lines is selected, the page memory allocation for a session becomes a single page and a scroll back buffer. You can then use Ctrl
and Ctrl keys to scroll up or down to review lines previously scrolled

off the screen. (Note: When this feature is enabled, the host cannot write to specific pages, and control codes from the host are ignored.)
