The
ESCAPE
key has
another
use.
Many
of
the
editing keys and special functions
we
have de-
scribed
do
something
other
than
put
a character
on the screen;
they
move the cursor, make
the
beep noise, and
do
many
other
things.
To
see
a character representing any
of
those
un-
usual functions displayed on the screen, press
the
ESCAPE
key once, and then press the special
function. For example, press the
ESCAPE
key and
then the
CONTROL-2
key combination. Instead
of
hearing the bell,
you
will
see the bell charac-
ter on the screen.
