Cursor
Movement
You
have probably noticed
by
now
that the

moves
the cursor
down
one
line.
You may
have
also
noticed that
most
of the
keyboard
keys
when
held
down
for
more
than
about one
half
second, repeat
their
function.

that
do
not
repeat
their
functions
are;
CTRL,
TTY
LOCK,
SHIFT,
BREAK,
RESET, COPY,
and
NUM
LOCK.
The

the cursor
in
the
direction of
the
arrow
on
the key.
Note
that
when
moving
the cursor
over displayed
data,
the data
is
not
affected.
These keys
provide
you
with
the
ability
to rapidly
move
the cursor
to
any
character position
on
the
display.
You'll find
them
very
useful.
