Adjustment handle

From HandWiki
Adjustment handles are a way to facilitate the construction of e.g. a cubic Bézier curve.

In graphical user interfaces, the control element adjustment handle is a small box that appears on the corners and edges of a selected element such as another graphical control element like a window. This allows the user to alter size or shape.[1]

By dragging and dropping the control handle onto an edge, the user can make the control wider or narrower, taller or shorter. Corner handles let one move two edges at once.[2]

An adjustment handle can also be used in audio editing software.[3]
