EASIER SCREEN VIEWING WITH CLOSEVIEW
CloseView is a program supplied with Macintosh system software that makes the
screen easier to view or read for people who have difficulty with standard-
size screen images.
You turn on CloseView and select its features in the Control Panel. With the
General section of the Control Panel open, locate and click the CloseView
icon to display the CloseView section of the Control Panel. Then select the
options you want to use.
The CloseView icon
Floppy startup disks: If you used the Installer to install system software
on a floppy disk, CloseView was not installed. You can install CloseView by
dragging its icon from the System Folder (System Startup disk) into the
System Folder of your floppy disk.
When CloseView is on, you will see its frame (a heavy box covering a portion
of the screen). The frame moves when you move the pointer on the screen.
When the frame is displayed, you can turn magnification on by pressing
Option-x-X. (The same keystroke turns magnification off.)
To increase or decrease the power of magnification, press Option-x-Up Arrow
(increase) or Option-x-Down Arrow (decrease).
