Modifier Keys

3.3.1 Modifier Keys

The [SHIFT], [CTRL], [ALT], [BLUE] and [ORANGE] keys are modifier keys. Pressing a modifier key changes the function of the next key pressed. For example, on a 63-key keyboard, 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 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.

3.3.1.1Activating Modifier Keys

When a modifier key is not locked ‘on’, 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 displayed at the bottom of the unit screen in lowercase letters.

When the next key is pressed, the modifier key becomes inactive and is cleared from the taskbar.

3.3.1.2Locking Modifier Keys

Note: The locking function of the modifier keys can be set up so that pressing one of these keys once will lock the key ‘on’. They can also be set up so that they must be pressed twice to be locked ‘on’. Refer to “Keyboard One Shot Modes” on page 93 for details.

When a modifier key is ‘locked’ on, it is displayed in uppercase letters in the taskbar. For example, if the [BLUE] key is locked on – it is displayed as BLUE KEY in the taskbar at the bottom of the screen.

The locked modifier key will remain active until it is pressed again to unlock or turn it off. Once a modifier key is unlocked, the uppercase representation in the taskbar is cleared.

3.3.2 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.
