A more recent innovation in mouse scrolling is a tilting scroll wheel that allows you to scroll onscreen both horizontally (left/right) and vertically (up/down). The ability to scroll both ways is handy when you are viewing wide documents like a Web page or spreadsheet.

To navigate both horizontally and vertically, the scroll wheel is positioned on a combination fulcrum and lever. This is the design used by the Logitech Cordless Click! Plus mouse.

Another method for vertical and horizontal scrolling is a touch scroll panel that responds to your finger sliding horizontally and vertically, as employed by the Logitech V500 Cordless Notebook Mouse.
