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 [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.
3.4.2 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.
The Arrow Keys
The Arrow keys move the cursor around the screen in the direction of the arrow—up, down,
left and right. The cursor is the flashing box or underline character that indicates where the
next character you type will appear.
The [INS] Key
The [INS] key inserts a character at the cursor position.
The [DEL] Key
The [DEL] key erases the character at the cursor position.
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 74
for details.
