To get the math symbols shown on the lower half
of these four keys, press each key alone : - ,
=,
+,
and
*.
SCREEN 1
If you have a BASIC cartridge, you can use these
four math symbols along with BASIC comman.ds
to
do mathematical calculations on your com-
puter. You 'll learn how
to
do this when you get
to the exercises on using the BASIC language.
To get the symbols shovVn on the top right of
these four keys, hold the SHIFT key as you press
each key: - ,
I , \ , /\ .
SCREEN 2
The arrows show you the control function of
each of these keys : the ARROW keys are used
with the CONTROL key to move the cursor to
any point on the screen.
You know one way to move the cursor forward
(using the SPACEBAR). But to move it up, down,
or backward you need different keys. Each
ARROW key moves the cursor in the direction in
which the arrow points. Using the ARROW keys
does
not erase anything, nor does it add any
characters to the screen display.
