Keyboard Character Sets; Using The Command Keys - Commodore 128 System Manual

Keyboard Character Sets

The Commodore 128 keyboard offers two different sets of
characters:
■ Upper-case letters and graphic characters
■ Upper- and lower case letters
ln 80-column format, both character sets are available
simultaneously. This gives you a total of 512 different characters
that you can display on the screen, ln 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
keyboard normally is 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 C* key (the COMMODORE key) at the same
time. To practice using the two character sets turn on your
computer and press several letters or graphic characters. Then
press the SHIFT key and the C* (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.

Some command keys (such as RETURN) are used by
themselves. Other command keys (such as SHIFT, CTRL, C' and
RESTORE) are used with other keys. The use of each of the
command keys is explained below. The keys used in C128 mode
are described in Section 5.
Return
When you press the RETURN key, what you have typed is sent to
the Commodore 128 computer's memory. Pressing the RETURN
key also moves the cursor (the small flashing rectangle that
marks where the next character you type will appear) to the next
line.
At times you may misspell a command or type in something the
computer does not understand. Then, when you press the
