Slider (computing)

A slider or track bar is a graphical control element with which a user may set a value by moving an indicator, usually horizontally. In some cases user may also click on a point on the slider to change the setting. It is different from a scrollbar in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen.

Its most popular use is for viewing and jumping to a playback position in media player software.
