Technical information

Your computer keyboard contains certain special keys that typewriter keyboards don’t have. Many of
these keys allow you to give commands to the computer without using the trackpad. For example, in
many application programs, pressing the
x (Command) key at the same time as the Q key lets you quit
the program.
Your keyboard looks like one of the illustrations on the next page. The illustrations, and the table that
follows, explain the function of all the special keys.
