Chapter 3: Getting to Know the 8515
The Keys
22 Psion Teklogix 8515 Vehicle-Mount Computer User Manual
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.
3.3.1.1 Activating Modifier Keys
When a modifier key is pressed once, it is displayed in lowercase letters in the taskbar at the
bottom of the 8515 screen. For example, if the [CTRL] key is pressed,
ctrl key
is dis-
played at the bottom of the unit screen. Once another key is pressed, the modifier key
becomes inactive and disappears from the taskbar.
3.3.1.2 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 [BLUE] key twice locks it
on—it is displayed as
BLUE 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 (pressed a third time), the uppercase representation at
the bottom of the screen is no longer displayed.
3.3.2 The Keys
The [BLUE] and [ORANGE] Keys
The [BLUE] and [ORANGE] modifier keys provide access to additional symbols and keys.
These additional symbols and keys are colour coded in
blue and orange print above the key-
board keys.
Press the [BLUE] key to access functions or characters displayed in
blue print on the key-
board. Press the [ORANGE] key to access functions or characters displayed in orange print
on the keyboard.
The [SHIFT/CAPS] Key
The [SHIFT/CAPS] key is used to display uppercase alpha characters. Pressing
[BLUE][SHIFT] turns the [CAPS] key on so that all alpha characters are printed in upper-
case until the [BLUE][SHIFT] sequence is pressed again.
Note: The locking function of modifier keys can be disabled so that pressing a modi-
fier key once will lock the key ‘on’. If you disable the ‘One Shot’ function of
these keys, pressing a modifier key once will lock it ‘on’. Pressing the same
key a second time will unlock or turn it ‘off’. Refer to “One Shots” on page 64
for details.
