DRVR-Desk Accessories (DA's to you enlightened ones out there); the little mini-programs one can find under the Apple menu in most programs. DRVR stands for driver. ResEdit makes it easy to move these in and out of your System file, operations that are also performed by Apple's (in)famous Font/DA Mover.
FONT-Fonts, found mainly in the System file. These, too, can be added to or removed from the System file with ResEdit just as they can with Font/DA Mover, however, ResEdit also gives you the ability to change the font's name, as well as freely alter any character(s) in it with an editor that works similar to Fatbits in MacPaint.
FKEY-Short for Function Keys, also mainly a part of the System file. Just as you can press Command-Shift-3 and get a MacPaint picture of the screen, or use Command-Shift-1 to eject the disk out of the internal drive, there are many other FKEY's now available that do everything from delete files to initialize disks to install screensavers.
