MOUSE BASICS Along with the keyboard, the mouse is the main way for most people to interact with their computer. Your mouse allows you to position the cursor on screen and select icons to open programs or adjust settings.
Traditional mouse• The typical mouse has a ball on its underside, to guide the position of the cursor, and two buttons on top. The left button opens programs or documents with a double-click and the right one allows you to view options related to the file, such as its properties.
Modern mouse• Many modern mouse designs use a laser instead of the mouse ball and feature a mouse wheel on top for scrolling quickly through documents, such as web pages.
Handy hints• Always use a mouse mat with a mouse that uses a ball. They are designed to help your mouse translate your hand movements accurately on screen.
• Buy a mouse mat with a padded wrist rest to help reduce the risk of repetitive strain injury.
