Apple Macintosh PowerBook 145 - Manual (Page 23)

Continuing your work
Next you see a message that asks whether you want to continue
using your Macintosh. To continue working or to learn how to use
the computer, use the trackball to choose Restart.
1. Place the index and middle fingers of your dominant
hand on the trackball and the thumb of the same
hand on the lower trackball button. Don’t press either
button yet.
2. Roll the trackball around with your fingers.
Notice that the arrow (8) on the screen moves in the direction
that you roll the trackball. For example, rolling the trackball to
the right moves the arrow to the right.
3. Roll the trackball so the arrow rests over the word
Restart.
Make sure that the tip of the arrow is inside the box with the
word Restart.
