Microsoft 673-00089 IntelliMouse

The IntelliMouse makes scrolling simple by rolling the wheel forward or backward (in Windows 95 - and Windows NT 4.0 based applications) instead of clicking on a scroll bar or arrow. Zoom quickly in or out by holding the CTRL key while rolling the wheel (in compatible applications). Work hands-free with Auto-Scroll. Press the wheel, set the scroll speed, then watch your document scroll automatically. Feel the comfort of Microsoft IntelliMouse. Its raised back fits the palm of your hand, and its side is curved so it's easy to hold - whether you're right-handed or left-handed.
