An history of scroll

A scroll is usually divided up into pages, which are sometimes separate sheets of papyrus or parchment glued together at the edges, or may be marked divisions of a continuous roll of writing material.

The first mouse

​

In 1985 NTT, Japan and ETH Zürich, Switzerland (Kunio Ohno, Ken-ichi Fukaya and Jürg Nievergelt) jointly invented and developed the first scrolling mouse. Their Mighty Mouse had the scroll wheel accessible on the side.[2] Somewhen between 1989 and 1993 Daniel S. Venolia of Apple developed another mouse prototype with a thumb-wheel accessible on the side.
