The Keyboard
Two keyboard options are available:
48-key alpha-numeric keyboard. This keyboard is only available with connected hand-
helds – units equipped with 802.11b/g radios.
26-key numeric keyboard. This option is available for both variants of NEO – 
connected hand-helds (described above) and batch (unconnected) hand-helds not 
equipped with 802.11b/g radios.
Most of the keys on these keyboards operate much like a desktop computer. Where a key or 
key function is not consistent with the PC keyboard, the differences are noted.
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 on the 
keyboard keys.
3.4.1
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.
3.4.1.1 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 82 f
or details.
3.4.1.2 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.
