Attribute Select Keyboards
Introduction
The Attribute Select keyboards consist of the following types:
• Attribute Select Typewriter keyboard
• Attribute Select Typewriter/APL keyboard
• Attribute Select Overlay keyboard
The Attribute Select keyboards will enable you to choose additional functions
called Highlighting and Programmed Symbols. Highlighting offers you the
following choices:
• Character Reversal (Reverse Video)
- Allows you to reverse the color of a character with the color of the
screen background. After the Select key is depressed, subsequent
characters entered will be reversed.
• Character Blinking
- When the Select Blink key is depressed, subsequent characters entered
from the keyboard will blink.
• Character Underscoring
- When underscore is selected, subsequent characters entered from the
keyboard will be underlined.
The Programmed Symbol Set feature permits you to store, under program
control, up to six character sets or fonts which are defined by your
organization. These can be selected by program or by you (if your program
allows you to and programmed symbols are installed) with the PF Keys.
Attribute Select Typewriter Keyboard
All the keys on the Attribute Select Typewriter keyboard (Figure 3-5), except
the PF13 -PF24 keys, perform the same functions and are located the same as
on the Typewriter keyboard, described earlier in this chapter. PFI3-PF24
keys are described later in this chapter under "Attribute Selection Keys."
Attribute Select Typewriter/APL Keyboard
The Attribute Select Typewriter/APL keyboard (Figure 3-6) is exactly the same
as the Typewriter/APL keyboard described in Chapter 4 except for the
assignment of the PFI-PF12 keys. These keys are described later in this
chapter under "Attribute Selection Keys."
Attribute Select Overlay Keyboard
The Attribute Select Overlay keyboard (Figure 3-7) is similar in layout and
operation to the Typewriter keyboard described earlier in this chapter. One
difference is that this keyboard has special narrow key tops (in the 48-key
data section only) which allow your organization to use its own specially
marked overlays. These overlays are used to indicate the special font symbols
associated with the keys whenever one of the Programmed Symbol sets is
selected. These keys are described next under "Attribute Selection Keys."
