Mouse Techniques

Placing your hand on the mouse.Place your hand on the mouse so that your index finger

is resting above the left mouse button and your middle finger is resting on the right button.

Double ClickingWhile your hand is resting on the mouse, use your

pointing finger to do a quick and light tap tap on the left mouse button. It is a very light tap tap, with less than a second between taps.

13

Without clicking, roll your mouse up and down this menu.
