pinned to the taskbar by default. You can pin the icon to the taskbar to make it
always visible when the touchscreen is locked; see Pinning keypad status icons to the
Taskbar for more information.
b. When the touch screen becomes locked the following notification is displayed and
the touch locked icon, indicated by the red arrow in the image below, is displayed on

15. Screen Display Brightness (Fn+7 Brighter; Fn+4 Dimmer). Adjust the display backlight
brightness. NOTE – You can also set the display brightness to adjust automatically when the
ambient lighting conditions change. See Display settings.
16. Back Tab
a. The back tab key performs the same function as pressing the Shift key and the Tab
key. For many applications this will move the focus to the previous control in the
sequence, as opposed to the Tab key which moves the focus to the next control. For
applications that use the Tab key for text entry it typically performs the same as the
Tab key.
Modifier keys and Sticky keys
The modifier (or shift) keys are keys that modify the action taken when other keys are pressed while
the modifier key is held down. Modifier keys can be used in combinations with more than one
pressed at the same time. The modifier keys are:
● the Shift key
● the Fn key
● the Ctrl key
● the Search key
● the AGr key
Since the device is normally hand-held, it can be difficult to press multiple keys on the built-in
keypad at the same time. To make the keypad easier to use, you can configure all modifier keys (Fn,
GUI/Meta, Shift, Alt,and Ctrl) as Sticky Keys. When enabled, the modifier keys “stick down” when
pressed so that they do not have to be held while the other key is pressed, allowing multiple key
combinations to be pressed by pressing the keys sequentially. For example, the Ctrl+Alt+Del
combination can be entered as press and release Ctrl, press and release Alt, and press and release
Del requiring only one finger to do what normally would require three.
