Using Caps Lock
The Caps Lock key on PowerBook computers does not stay
depressed even when it’s locked. You can tell whether Caps Lock
is on or off by looking at the menu bar. An arrow appears to the
left of the Help menu icon when Caps Lock is on.
To turn Caps Lock on or off, press the Caps Lock key.
Typing special characters and symbols
You can type a variety of special characters (with diacritical marks)
and symbols by pressing modifier keys in combination with
certain letter and number keys.
The Key Caps program, which is installed with the system
software, shows you the characters produced when you type
certain keys and key combinations in the fonts available on your
computer. Choose Key Caps from the Apple (K) menu, then
