The scroll wheel on a mouse has been invented multiple times by different people unaware of the others' work. Other scrolling controls on a mouse, and the use of a wheel for scrolling both precede the combination of wheel and mouse. The earliest known example of the former is the Mighty Mouse prototype developed jointly by NTT, Japan and ETH Zürich, Switzer
[2] Scrolling can be controlled in other software-dependent ways by a PC mouse. Some scroll wheels can be pressed down, functioning like a button. Depending on the software, this allows both horizontal and vertical scrolling by dragging in the direction desired; when the mouse is moved to the original position, scrolling stops.

[1] [2] In this usage, Scroll Lock is a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is released. Today, this particular use of Scroll Lock is rare.
The effective limit may still be too fast for certain conditions, such as limited visibility or reduced road traction [110] or even low-speed truck rollovers on exit ramps. [111] Variable speed limits offer some potential to reduce speed-related crashes. However, due to the high cost of implementation, they exist primarily on freeways ...
