C=KEY
C= PLUS THE LETTER KEYS
How do you display the symbols that appear
on the left side of the letter keys? This is easily
done by holding down the C key while
pressing each letter key. The C key is popu
larly called the bird key because it resembles a
bird's head and beak. If you use the C - key
with a key that doesn't have graphic symbols,
you get the same symbol as if you had held
down the SHIFT key. The C - key has
other functions as well, which you will learn
about soon.
For now, hold down the C key and press
each of the letter keys. [Be sure not to hold
SHIFT and not to have the SHIFT LOCK key
down.) Watch as the left-hand graphics sym
bols appear on the screen, following the right-
hand symbols you typed before.
SCREEN 1
Previously, when you pressed a letter key by
itself, the letter appeared in uppercase on the
screen. There may be times, however, when
you will want to use both upper- and lower
case letters. You can do this by entering the
Text Mode.
USING SHIFT AND C= KEYS TOGETHER
To turn on the Text Mode, you hold down a
T key and press the C - key. Try this now.
• The uppercase letters have turned into
lowercase letters.
• The graphics symbols that appeared when
you used SHIFT plus a letter key have turned
into uppercase letters.
• The graphics symbols created by pressing the
key with a letter key remain unchanged.
SCREEN 2
Do not turn off the computer before going on
to the next exercise.
