Keyboard Character Sets
The Commodore 128 keyboard offers two different sets of
characters:
■ Upper-case letters and graphic characters
■ Upper- and lowpr case letters
In 80-column format, both character sets are available simultane
ously. This gives you a total of 512 different characters that you can
display on the screen. In 40 column format you can use only one
character set at a time.
When you turn on the Commodore 128 in 40-column format, the key
board is normally using the upper-case/graphic character set. This
means that everything you type is in capital letters. To switch back
and forth between the two character sets, press the SHIFT key and
the O key (the COMMODORE key) at the same time. To practice
using the two character sets turn on your computer and press sev
eral letters or graphic characters. Then press the SHIFT key and the
O (Commodore) key. Notice how the screen changes to upper- and
lower-case characters. Press SHIFT and C* again to return to the
upper-case and graphic character set.
Using the Command Keys
COMMAND keys are keys that send messages to the computer.
Some command keys (such as RETURN) are used by themselves.
Other command keys (such as SHIFT, CTRL, O and RESTORE) are
used with other keys. The use of each of the command keys is
explained below.
Return
When you press the RETURN key, what you
have typed is sent to the Commodore 128 com

moves the cursor (the small flashing rectangle
that marks where the next character you type
will appear) to the beginning of the next line.
At times you may misspell a command or type in
something the computer does not understand.
Then, when you press the RETURN key, you
