The [SHIFT] Key
The [SHIFT] key is used to display uppercase alpha characters. Pressing [BLUE][SHIFT] turns the [CAPS]
key on so that all alpha characters are printed in uppercase until the [BLUE][SHIFT] sequence is pressed
again.
The [CTRL] and [ALT] Keys
The [CTRL] and [ALT] keys modify the function of the next key pressed and are application dependent.
Pressing either key twice locks it 'on' (it appears underlined on the Taskbar). Pressing the key once again
unlocks it.
The [TAB] Key
Typically, the [TAB] key moves the cursor to the next field to the right or downward.
The [ESC] Key
Generally, this key is used as a keyboard shortcut to close the current menu, dialog box, or activity.
The [SPACE] Key
Pressing this key inserts a blank space between characters. In a Windows dialog box, pressing the [SPACE]
key enables or disables a check box.
The [INS] Key
The [INS] key inserts a character at the cursor position.
3.2.2 Modifier Keys
The [SHIFT], [CTRL], [ALT], [BLUE] and [ORANGE] keys are modifier keys that change the function of the
next key pressed. The functions related to the [BLUE] modifier key are colour-coded in blue print above the
keyboard keys.
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.
3.2.2.1 Activating Modifier Keys
When a modifier key is pressed, it is shown in the softkey bar at the bottom of the screen, making it easier
to determine whether a modifier key is active. For example, if the [CTRL] key is pressed,
Ctrl is displayed at
the bottom of the unit screen. Once the next key is pressed, the modifier key becomes inactive and disap-
pears from the taskbar.
3.2.2.2 Locking Modifier Keys
When a modifier key is pressed twice, it is ‘locked’ on. A ‘locked’ modifier key is displayed underlined in the
taskbar. For example, pressing the [BLUE] key twice locks it on — it is displayed as an underlined blue box in
the taskbar at the bottom of the computer screen. The same is true of the [ORANGE] key, which is shown as
an underlined orange box in the taskbar.
The locked modifier key will remain active until it is pressed a third time to unlock or turn it off. Once a mod-
ifier key is unlocked, the underline representation at the bottom of the screen is no longer displayed.
3.2.3 Function Keys and Macro Keys
In addition to the standard keyboard functions (see “The Keyboard” on page 15), the VH10 supports func-
tion keys and macro keys.
Note: The locking function of the modifier keys can be changed so that pressing a key once will
lock the key ‘on’.
If you disable the ‘One Shot’ function of the key, pressing it once will lock the key ‘on’. Press-
ing the same key a second time will unlock or turn it ‘off’. Refer to “One Shot Modes” on
page 59 for details.
