The mouse

A mouse is a hand-held device that lets you move a pointer (or cursor) and select items on the screen. It has one or more buttons to communicate with the PC. A scroll wheel lets you move through your documents or web pages. The pointer looks like an l-bar, an arrow or a pointing hand. An optical mouse has an optical sensor instead of a ball underneath. A cordless (wireless) mouse has no cable; it sends data via infrared signals or radio waves. Mouse actions:

• to click, press and release the left button.
• to double-click, press and release the left button twice.
• to drag, hold down the button, move the pointer to a new place and then release the button.
• to right-click, press and release the right button; this action displays a list of commands.
