As in System 6, FKEYs must be installed using a "resource moving" utility like ResEdit (version 2.0 or later).
Installing System 7 over a previous system does not remove FKEYs that were already installed in your system.
Note: The screen-capture FKEY (invoked by pressing Command-Shift-3) has been much improved in System 7. When you press Command-Shift-3, the system takes a "snapshot" of your screen and creates a TeachText file of the image. The resulting file contains an accurate image of your screen, even displaying colors and the image from multiple attached monitors.
Warning: The instructions in this article refer to using ResEdit. Apple Computer, Inc., is not liable for any damage done to your software through the use of ResEdit to alter software.
