CONTROLLING
THE
MOUSE
The mouse
is a
small box
with
two
buttons
on top
and
a
small
ball
underneath.
It
detects
motion
(direction,
distance,
and speed)
through the
movement
of
the
small
ball.
The
left
mouse
button
is
used
to
“select”
and
move
icons and
files. The
right
button is
used
with
some
software
programs.
To
understand
how the
mouse
operates,
place
it
on
a
flat
surface
so
that
the side
with
the
cable
is facing
the
computer.
Then
move
the
mouse
around
—
left,
right,
forward,
backward,
in
circles.
On
the
monitor
screen
a
small
arrow
called
the
“mouse
pointer”
follows
the
movements
of the
mouse.
