Chapter 5: Getting To Know The Warrington
Modifier Keys
Warrington Hand-Held Computer User Manual 61
The [FN/BLUE] and [FN/ORANGE] modifier keys provide access to additional keys and
system functions. These functions are colour coded in orange and blue print above the
keyboard keys.
5.4.1 Modifier Keys
The [SHIFT], [CTRL], [ALT], [FN/BLUE] and [FN/ORANGE] keys are modifier keys.
Pressing a modifier key changes the function of the next key pressed.
The [SHIFT], [CTRL] and [ALT] keys operate much like a desktop keyboard except that
they are not chorded (two keys held down simultaneously). The modifier key must be
pressed first followed by the key whose function you want modified.
5.4.1.1 Activating Modifier Keys
When a modifier key is pressed once, it is displayed in lowercase letters in the taskbar at the
bottom of the hand-held screen. For example, if the [CTRL] key is pressed, ctrl key is dis-
played at the bottom of the unit screen. Once the next key is pressed, the modifier key
becomes inactive and disappears from the taskbar.
Keep in mind, however, that the ‘One Shot’ function allows you to determine how many key
presses will lock a modifier key ‘on’ – one press or two. Refer to “Keyboard One Shot
Modes” on page 90 for details.
5.4.1.2 Locking Modifier Keys
When a modifier key is pressed twice, it is ‘locked’ on. A ‘locked’ modifier key is displayed
in uppercase letters in the taskbar. For example, pressing the [CTRL] key twice locks it on –
it is displayed as CTRL KEY in the taskbar at the bottom of the computer screen.
The locked modifier key will remain active until it is pressed a third time to unlock or turn it
off. Once a modifier key is unlocked, the uppercase representation at the bottom of the
screen is no longer displayed.
5.4.2 The Keys
The [SHIFT] Key
The [SHIFT] key is used to display uppercase alpha characters and provide access to the
symbols above the numeric keys.
