Mouse

The mouse is a peripheral that is known as a pointing device. It lets you point to objects on the screen, click on them, and move them. Previously, it was considered an optional device, but now all desktop computers will come with a mouse.

There are two main types of mice -- optical and mechanical. The optical mouse uses an electronic eye to detect movement and is easier to clean. The mechanical mouse uses a rolling ball to detect movement and is more difficult to clean; however, it is less expensive, so many computers come with a mechanical mouse. 

Another decision you have when choosing a mouse is wired versus wireless. Wireless everything is popular right now, so it will be up to you to decide which type will work best for you.

To properly use the mouse:

• Using your right hand, place your thumb on the desk or table top on the left side of the mouse
• Your index (pointer) finger should rest on the left button of the mouse.
• Place your middle finger on the right button of the mouse.
• Your ring finger and little finger should rest on the right side of the mouse.
• The base of your wrist should rest on the mouse pad or desktop, for stability.

Left-handed computer users sometimes use their right hand to maneuver the mouse. However, if you're left-handed and want to use your left hand, the mouse buttons can be switched.

To Switch the Mouse Buttons for a Left-Handed User:

• Click Start.
• Choose Settings Control Panel.
• Double-click the Mouse icon in the Control Panel window.
• Click Left-handed.
• Click OK.

To properly use the mouse:

·         Click. Select an object on the screen by pressing the left mouse button down with your index finger and then release the button.

·         Drag an object on the screen by pressing and holding down the left mouse button with your index finger while moving the mouse. When the object is where you want it, release the button.

·         To double-click, rapidly press and release the left mouse button with your index finger.

·         To right-click, press and release the right mouse button with your middle finger.

A trackball is similar to a mouse, but the ball that helps maneuver the cursor is on top instead of underneath.
