Apple Macintosh LC - Manual (Page 111)

Locking and unlocking documents
You use the Get Info command to lock or unlock a document, whether on a
floppy disk or a hard disk.
1. Select the icon of the document you want to lock.
2. Choose Get Info from the File menu.
The Info window appears.
3. Click the Locked box in the upper-right corner of the Info window to
change the status of the document.
When there is an "X" in the check box, the document is locked.
When the check box is empty, the document is unlocked.
4. Click the Info window's close box.
You can also use Get Info to lock a program (to prevent the program's being
erased, for example), but locking a program may affect its operation. If you
have a problem with a program you have locked, just unlock it.
CHAPTER 14-ADDING AND REMOVING FONTS AND DESK ACCESSORIES
The Macintosh system software includes several desk accessories and a
selection of type fonts. Independent manufacturers and user groups or
computer bulletin boards provide many additional fonts and desk accessories.
When you install the system software, a core set of fonts and desk
accessories is installed. You can add more desk accessories or fonts -- or
remove any of the ones already installed -- with the Font/DA Mover, another
part of the system software supplied with your Macintosh.
Fonts and desk accessories are installed in the System file of a startup
disk. Any font in the System file of the current startup disk is available to
you in any program that uses fonts. Any desk accessory is available from the
Apple menu whether you are working on the desktop or in a program.
In addition, you can store extra fonts or desk accessories in separate files
-- called fonts files and desk accessories files -- which are represented by
a suitcase icon. These files can be used to transfer fonts and desk
accessories from the system file on one disk to the system file on another
disk. They can also be used to store fonts and desk accessories that you do
not want to install (to save disk space on a startup disk) but want to keep a
copy of for later use.
Fonts and desk accessories stored in these suitcase files are not available
for use until you install them in the System file on each of your startup
disks.
Installing a font or desk accessory
You can easily install one or more new fonts or desk accessories in the
System file of a startup disk. (If you use floppy startup disks, you may be
somewhat limited by disk capacity.)
