Apple IIe Card - Manual (Page 40)

Changing the Type Ahead setting
You use the Type Ahead feature to type text and commands while the Apple IIe
program is busy with some other activity. Even though you may not see the
text immediately on the screen, what you type is stored in a type-ahead
buffer, an area of memory reserved for keeping track of what you type.
Some programs do not perform correctly when the Type Ahead feature is on. If
the keyboard seems unresponsive in a particular program, or if certain keys
don't work as expected, try turning the Type Ahead feature off.
To change the Type Ahead setting, follow these steps:
1. Press Control-Command-Esc.
The Option Panel appears, with the General Controls panel displayed. The
pointer changes to a crosshair when you place it in the General Controls
panel.
2. Click the button for the setting you want.
Clicking the Off button turns off the Type Ahead feature; clicking the On
button turns it on.
After you close the Option Panel, your choice remains in effect until you
change the setting again.
Changing the Display setting
If you have a color monitor, you can choose between a color or monochrome
display. Even with a color monitor, however, there are times when working in
monochrome is an advantage. First, because of the manner in which the Apple
IIe produces color, you may see "color fringing" -- a slight color cast
around the edges of text characters. If so, switching to monochrome avoids
the problem.
By the way: You can improve the computer's processing performance in the
Apple IIe environment if you set the Display setting to Monochrome in the
Option Panel.
To change the Display setting, follow these steps:
1. Press Control-Command-Esc.
The Option Panel appears, with the General Controls panel displayed. The
pointer changes to a crosshair when you place it in the General Controls
panel.
2. Click the button for the setting you want.
After you close the Option Panel, the Display setting you chose remains in
effect until you change the setting again.
Changing the character set
Apple IIe programs normally display text with a light character set on a dark
background. You can change this to dark text on a light background by
choosing the inverse character set.
