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.
