Proper Setup and Use

Table 1 (Cont.) Recommendations for Proper Setup and Use
Adjust

To . . .

Terminal

Eye level and at the correct distance for proper vision.

Eyes

Avoid eye fatigue, which can be caused by glare, image quality,
uncomfortable furniture, eye height, and uncorrected vision. If you
cannot read the screen at different distances, you may need special
glasses. Relax your eyes periodically by looking at distant objects.

Work
Breaks

Take periodic work breaks. Morning, lunch, and afternoon breaks
meet most recommendations. Take advantage of work breaks to
move around and do other movements.

Lighting

Avoid direct lighting or sunlight on the screen, which causes glare
and reflections. This terminal screen has an antiglare treatment to
reduce glare. Place lighting behind or to the side of your work area,
and distribute the lighting evenly on your work area. Adjust the
brightness and the contrast controls as needed.

Noise

Keep background noise at a minimum. Background noise above
65 dBA is tiring. Sound-absorbing materials, such as curtains,
carpeting, and acoustic tile, can help reduce background noise.

Temperature

20°C to 23 °C (68°F to 74°F)

Humidity

30% to 70%

Ventilation

Provide adequate air ventilation for equipment operation and to
avoid fatigue.

Space
between
terminals

More than 70 cm (28 in) center to center, preferably more than 152
cm (60 in).

Warning
If you experience pain or discomfort during use of the
terminal, then take a substantial break and review the
instructions for posture and work habits. If the pain or
discomfort continues after resuming use of the terminal,
then discontinue use and report the condition to your job
supervisor or physician.

or to perform local terminal functions such as
the arrow keys ( , , , ), the Shift modifier
key, or the Set-Up key.

Alphanumeric:

Modifier Keys

Keys used to transmit alphanumeric
characters.

Modifier keys vary from within the function and alphanumeric
categories. A modifier key is a key that modifies the behavior
of other keys when it is pressed and held down. For example,
pressing an alphanumeric key in combination with the Shift
modifier key will normally send the shifted or uppercase
characters for that key.
Modifier keys are treated as a special kind of local terminal
function. The VGB10 function modifier keys are: Shift , Ctrl , and
Alt . VGB10 alphanumeric keys can also be modified by pressing
Group Shift ( Alt Gr on enhanced PC keyboards) and Alt Shift
(Shift-2). Modifier keys themselves cannot normally be modified
by other keys. A key assigned to act as the Shift modifier, for
example, cannot transmit a function sequence when pressed in
combination with the Alt key. Defining a key as a modifier key
makes all assignable combinations of that key act as a modifier.

Creating a New
Function

To define a new function key:
1. From the Keyboard menu item, select the Define
key . . . function, and the Define Key Editor menu
will appear.
2. Press the key for which you want to assign a new behavior.
and
keys to highlight the "Function" radio
3. Press the
button ( Function) and press Enter .

4. Press the
and
keys to highlight the modifier
combination that you want to define (unshifted, shifted,
control, and so on) and press Enter .

5. Press the
key to move to the "Select function" scroll box.
Press the
and
keys to highlight the desired keystroke
function from the list and press Enter .

4–2 Defining Keys

Define Key Editor

6. Press the

key to return to the modifier selection.

7. Repeat steps 4 through 6 to define other modifier
combinations as desired.
8. Use the arrow keys ( , , ,
pushbutton and press Enter .

) to highlight the OK or Apply

Correcting a
Mistake

If you make a mistake or want to start over, select the Cancel
pushbutton or select the Exit Set-Up menu item. Your
changes will not be recognized until you select the OK or Apply
pushbutton. To save your key definitions so they will be available
the next time you turn on the system power, select the Save key
definitions menu item from the Keyboard menu.

Examples of
Uses

Examples of when to create new functions include:
•

To change the < x key to delete when unshifted and to
backspace when shifted

•

To disable the Compose , Break , or Set-Up key by assigning
them to have no function

The Define Key Editor can be very powerful if you take the time
to learn how to use it. No matter how you redefine the keys,
you can always enter Set-Up by pressing F3 after powering on.
Additionally, you can always restore the factory default settings
by invoking the Actions menu item.
Note
See the VGB10 Video Terminal Programmer Information
manual to redefine alphanumeric keys or keyboard
layouts.

Keyboard Function Keys
User Definable Keys
Overview

All keyboard keys are programmable by selecting the Define
key function from the Keyboard menu item in Set-Up. They
can be programmed to send single characters or character
sequences, or to invoke a local function, such as Print Screen.
The function keys have the following key levels: Unshifted,
Shifted, Control, Shift Control, Alt, Alt-Shift, Alt-Control, and
Alt-Shift-Control.

Local Functions
Overview

The keys used to perform local terminal functions differ
between the VT keyboard, PC keyboard, and the mode selection.
Table B–1 shows the corresponding keys for the default local
functions and their function number. This number is used in
the DECPFK host sequence or DECPAK’s alternate function
to specify a change to that Local Function key. Table B–2 lists
other available local functions.
