Using Caps Lock
The Caps Lock key on PowerBook computers does not stay
depressed even when it’s locked. Caps Lock is on when the light
on the key itself 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
choose the font from the Key Caps menu.
Characters appear here when you press keys on
the keyboard or click them in the window.
