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."
