Touchpad Basics
The following items teach you how to use the touchpad:
! Move your finger across the touchpad to move the cursor.
!
Press the left (1) and right (3) buttons located on the edge of the touchpad to do selection and
execution functions. These two buttons are similar to the left and right buttons on a mouse.
