What does slider mean?
A slider is a movable control that travels along a track, allowing someone to adjust a setting, select a value, or move through information. In digital interfaces, sliders are used for tasks such as changing volume, brightness, playback speed, or the position in a video. The same word also names a baseball pitch that moves rapidly toward the plate while breaking laterally near the end of its path. In North American food usage, a slider is a small hamburger or sandwich served in a soft, elongated roll. Mechanical and engineering contexts use the word more broadly for a component that slides along a guide or surface. Although the word can refer to several different objects, these senses share an image of something controlled by a smooth, sliding movement.

A slider turns a simple adjustment into a gesture: one small movement can change everything from image brightness to playback speed.

Where does slider come from?
The word combines the English verb slide with the suffix -er, an agent or instrument marker that can indicate someone or something performing an action or associated with one. Its earliest uses developed from the general idea of something that slides, before the familiar electronic control sense became established in computing.
How slider is actually used
The interface-control sense is standard in computing and digital media. The baseball sense is familiar in North American English but also used in general sports writing. The food sense, meaning a small sandwich in a soft roll, is chiefly North American and informal.
Easily confused with slider
A slider is usually a movable control or component, whereas a slide is the action of moving smoothly across a surface or the surface itself.
