to
the

if
there
is

Overwrite
Input
Mode
(Linear
Display
only)
You
can
select
either
insert
or
overwrite
as
the
input
mode,
but
only
while

replaces
the

can
toggle
between
the
insert

overwrite
modes
by
performing
the
operations:
(ot)
(INS).
The
cursor
appears
as
“Il”
in
the
insert
mode
and
as
“mm”
in
the
overwrite
mode.
Note:
Natural

always
uses
the
insert
mode,

from
Linear
Display
to
Natural

will
automatically
switch
to
the
insert
mode.
