You communicate with
your computer through
the keyboard. You can
do a ~otmore, however,
than Just type on this key-
board. You can throw
away your ink eraser and
editing pencils, for you
can transform text and
programs with a few key-
strokes. NOTE: The white

Though the ATARI 800XL
keyboard looks and
works much like a type-
wnter, there are keys
that allow you to reach in-
to a bag of editing tricks.
CONTROL and SHIFT
are particularly important
in editinc and in gener-
atmg graphics and inter-
national characters. They
move the cursor delete
or insert charact'ers or
sentences, or change
from upper-case to
lower-case letters.
Another key must be
pressed while holding
down CONTROL or
SHIFT for a command to
be executed.
Since a key's function
may change in certain
programs, always consult
your program user's
guide.
The next few pages
show some of the com-
mands you use to tell
your computer what to
do.
