Apple lore: Early
models
of
the
Apple
II
didn't
have
a
Caps
Lock key
because
all
letters
appeared
in
uppercase.
Consequently,
programs
designed
for
early
models
of
the
,\pple
II
don't
recognize lowercase leiters
and
either
don't
respond
to
your
typing
or
issue an
error
message
like
SYNTAX
ERROR.
To
get
these
programs
to
run
correctly
on
your
Apple lie, you must press Caps Lock down.

Keys
that
move
the
cursor
In
programs thai have a cursor, the cursor's initial position
is
usually in the upper-left
corner
of
the scrccn.
The
cursor moves
10
the right with every character
you
type. In
many
programs,
particularly
word
processing programs,
the
cursor moves
to
the
nexIline
automatically,
when
it
reaches
the
end
of
a line (you don't
have to press Rerum). This is called
wraparound.

Arrow moves the cursor
one
character

Apple lore: Early models
of
the
Apple
II
didn't
have
up
and
down
arrow keys,
so
programmers
reprogrammed
certain keys
for vertical
cursor
movements.
Different
programmers
chose
different ways
to
do
this.
If
you work with a program that doesn't
take
advantage
of
the
arrow
keys, check
the
program's manual
for
cursor
movement
commands.
