When pressed at the same time as the CON-
TROL key, the FUNCTION keys serve other pur-
poses. CONTROL and Fl deactivates the key-
board; then you can leave the computer on
without changing what is in the computer's
memory if anyone were to type on the key-
board. CONTROL and F2 stops the display on
your screen; the computer can then operate
faster if it is not using any of its memory for
video output. CONTROL and F3 stops the small
beep sound made when you press a key CON-
TROL and F4 allows you to display the inter-
national language characters that are built into
the 1200XL's keyboard. Let's try it.
First clear the screen by pressing a SHIFT key
and the CLEAR key Starting in the top row of
letter keys, press each LETTER key once, in the
order they appear on the keyboard. Then add a
semicolon, a comma, and a period.
