At the bottom of the screen are typically two rows of buttons (they may be covered by the text window). The top row are the "System Buttons" and they let you view different types of computer components. When these buttons are highlighted, their name appears in the item box just below the picture area.
The System Buttons are Computer Systems, Displays, Disk Drives and Storage, Printers and Plotters, Keyboards and Input Devices, Motherboard, Software, and Cables and Connectors.
