Modifier Keys
3.4.1 Modifier Keys
The <SHIFT>, <CTRL>, <ALT>, <ORANGE> and <BLUE> keys are modifier
keys. Pressing a modifier key changes the function of the next key pressed. For
example, a square bracket is printed in orange print above the <4> key. Pressing the
<ORANGE> key followed by the <4> key displays a square bracket rather than the
number 4.
The <SHIFT>, <CTRL> and <ALT> keys operate 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 screen. For example, if the <CTRL> key is pressed
once,
ctrl key is displayed in the taskbar. Once the next key is pressed, the modifier key
becomes inactive and disappears from the taskbar.
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 in the taskbar is no longer displayed.
Note: The locking function of the <ORANGE> and <BLUE> keys can be dis-
abled so that pressing either of these keys once will lock the keys ‘on’.
Refer to Keyboard One Shot Modes” on page 69 for details.
3.4.2 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. Pressing this key twice locks it ‘on’ so that
when you press an alpha key, an upper case character is displayed. When you press
a numeric key, the associated symbol on the numeric key is displayed
