device built to help the user control this on-screen pointer in as natural and efficient a manner as possible. The pointer on the screen mimics the movements of your mouse. As you move your mouse, a ball encased in the bottom of your mouse rolls on the desk and in turn sends signals to the computer as to which direction to move the pointer on the screen. Move the mouse side to side, or up and down, and the on-screen pointer moves in a similar manner. Once you have the mouse positioned to select the command or data you want to act on, you use the mouse buttons to execute the command.The mouse controls the on-screen pointer and lets you select program icons, manipulate property sheets, and access data. Connecting a Mouse Your mouse connects to your PC either through a dedicated mouse port or a standard 9- pin serial port. Once you're familiar with what the mouse connectors look like you can go ahead and connect your mouse using the following steps: 1. Save any open documents, and then close all active applications. 2. Identify which type of mouse connector you have and its corresponding connector on the back of your computer. 3. Carefully position the connector so that it matches the connector on the back of your PC, and gently press it into place. 4. In most cases, you'll have to restart your computer in order for the operating system to recognize your mouse. Using the Mouse Buttons Most mice have two buttons. In Windows 95, the left button selects text and data, executes commands, and manipulates data, while the right mouse button accesses context menus. Pressing a mouse button and then releasing it is known as clicking your mouse. You can click both left and right mouse buttons. Pressing the button and releasing it twice in quick succession is called double-clicking. The Left Mouse Button It seems simple, but there are a lot of things you can do by combining various types of mouse clicks with mouse movements. Table below gives you some examples. Table: Left Mouse Button Operations Task Mouse Button Select items Press and hold down the left mouse button. Move the mouse to select desired text, numbers, or objects. Release mouse button. The selected text is highlighted. Move selected items (also called click and drag) Position mouse over highlighted text. Press and hold left mouse button down.
