A button-like image displayed on screen. When you move the pointer over the button on the screen and click on the mouse, something happens. For example, when you want to leave Windows it displays a small box with the message "Are you sure you want to leave?" and two buttons labelled OK and Cancel. If you move the pointer over the OK button and click, you'll quit. In Windows 95 there's always a Start button in the bottom left of the screen. If you move over this and click you'll see a menu of options. There are all sorts of buttons, but radio buttons and push-buttons are the most common. A radio button lets you choose only one from a number of options, while a push-button sets off an action. In many multimedia programs, or on a Worldwide Wide Web page on the Internet, you'll see images that are used as buttons, or areas of the screen that start an action if you click them. These are called hot-spots. If you use a Windows application, such as Microsoft Word, or Works, you'll see a line of tiny buttons along the top of the screen, just below the menu bar. This is called a button-strip or button bar. Each button has a tiny picture called an icon that tells you what will happen when you click it.
