2.3.1 Modifier Keys
The <CTRL>, <ALT>, <ALPHA/ORANGE> and <FN/BLUE>
keys are modifier keys. Pressing a modifier key changes the function
of the next key pressed. For example, alpha keys are displayed in
orange print above the numeric key <1>. Pressing the <ALPHA/
ORANGE> key followed by the <1> key displays the letter a rather
than the number 1 .
The <CTRL> and <ALT> keys operate much like a desktop key-
board except that they are not chorded – two keys cannot be held
down simultaneously. The modifier key must be pressed first fol-
lowed by the key whose function you want modified.
Activating Modifier Keys
When a modifier key is pressed once, the modifier key icon displays the
key in lowercase letters in the taskbar. For example, pressing <CTRL>
once displays ctrl key in the taskbar. Once the next key is pressed, the
modifier key becomes inactive and disappears from the taskbar.
Locking Modifier Keys
When a modifier key is pressed twice, it is ‘locked’ on. A ‘locked’
modifier key icon displays the key in uppercase letters in the taskbar.
For example, pressing the <FN/BLUE> key twice locks it on – it is
displayed as BLUE KEY in the taskbar at the bottom of the screen.
The locked modifier key remains active until it is pressed a third time
to unlock or turn it off.
