Introduction
Fade to Black is a Desk Accessory designed to save your Macintosh screen.
It's possible for the image on a computer's screen to get "stuck" when it is
displayed for a long time, and remain visible, even when something else is on
the screen. This is more of a problem on a Mac than other computers, because
much of the Macintosh's screen is white. But the problem is also easier to
solve on a Mac than other computers, because of the flexibility of the Mac's
operating system. This is what Fade to Black does.
Fade to Black works by waiting quietly until you haven't used your Macintosh
for a while, and then causes the screen to slowly fade to black, so the image
that was being displayed won't become permanent. To let you know that your
Mac's still alive, a copy of the current application's icon floats around the
screen. When you want to use the Mac again, simply click the mouse button or
press a key, and the screen will be restored.
Using Fade to Black
Fade to Black is simple to use. First, install it on any system disks you
have. Because some software may not work with Fade to Black, you should
always install Fade to Black on a copy of the disk, not the original. To
install it, use the Font/DA Mover to copy Fade to Black to the system file
on your disks.
The first time you select Fade to Black from the menu, a small routine
(known as an INIT resource) will be copied from the desk accessory to the
system file. This routine allows Fade to Black to run automatically
whenever you boot from the disk with Fade to Black on it.
If your Macintosh beeps when you open Fade to Black, the INIT resource
couldn't be placed in your system file. One possible cause of this is that
you already have too many INIT resources (only 32 are allowed). For most
people, this won't occur (most system files normally have five to ten INIT
resources). The most common cause is simply that the disk containing the
system file is write protected. In this case, the routine has been placed in
memory, but not on disk, so it will remain only until you reboot.
When you have selected Fade to Black, and the INIT resource has been written
to disk if necessary, a dialog box will be displayed which allows you to set
the time delay to wait before fading, whether or not to make Fade to Black
permanent, and a button which allows you to Fade... immediately. The
permanent item allows you to specify whether or not Fade to Black should
fade the screen automatically. If it isn't checked, you will have to manually
fade the screen by clicking in the Fade box. If the permanent item is
checked, Fade to Black will wait until you haven't typed a key, or pressed
the mouse button, for the delay time specified.
When you have set the delay time and the permanent status, you can save the
values to disk by clicking in the OK box. If the disk containing the system
file is write protected, the values will only be saved in memory, and will be
lost when you reboot.
If you change the values of the delay time or the permanent status, and don't
wish to save the changes, you can click in the Cancel box.
To cause the screen to fade immediately, you can click in the Fade box. Any
changes you have made to the delay time or permanent status will not be saved.
Once the screen is cleared, you can restore the screen's contents by typing a
key, or clicking the mouse button. The key or the mouse click will not be
seen by whatever application is running. If you are in MacWrite for instance,
the key you type will not be entered in your text.
Shortcuts
When the Fade to Black dialog box is being displayed, you can use two
shortcuts. First, you can press the Return key. This is the same as clicking
in the OK box. You can change either the delay time, or the permanent status,
and then press Return, and it will be saved to disk as if you clicked in the
OK box.
Second, pressing Enter is the same as clicking in the Fade box. To quickly
fade the screen, you can select Fade to Black from the menu, and press
enter to fade the screen.
When the screen has faded, and the application's icon is being displayed,
holding down the Option key will cause the screen to be restored. When you
release the Option key, the screen will quickly be cleared. While the Option
key is held down, the application that is running will be active. You can
then work with the application, and even quit or transfer to another
application. When the Option key is released, the screen will be cleared and
the current application's icon will be displayed.
Removing Fade to Black
If you should ever want to remove Fade to Black, you can simply remove it
using the Font/DA Mover. The next time you boot from the disk that used to
contain the desk accessory, the INIT resource will recognize that you removed
Fade to Black, and will remove itself.
Compatibility
Fade to Black has been tested with a number of applications, such as the
MiniFinder, MacTerminal, and Switcher, although it is impossible to test it
with every application. In general, if an application provides an menu and
allows desk accessories to be selected, it should work with Fade to Black.
If the application doesn't allow desk accessories, Fade to Black may still
clear the screen automatically, but of course you won't be able to select
Fade to Black and change the delay value or the permanent status. Such is
the case with the MiniFinder.
Fade to Black takes approximately 1300 bytes on the application heap, when
it has been selected from the menu, and 900 bytes on the system heap, so
some applications which allocate all of the memory they can get will not work
with Fade to Black.
Passing on Fade to Black
Everyone is encouraged to pass on Fade to Black, as long as you pass on this
documentation as well as the desk accessory, and my name, the version number,
and the copyright date remain intact in the dialog box. You may not sell
Fade to Black, or use it as an inducement to purchase another product.

obligation to send me anything (although it would be appreciated). My address
