A row or column of on-screen buttons used to activate functions or change modes in an application. Many toolbars are customizable, letting users add and delete buttons as required. Toolbars may be fixed in position or float around the screen. For example, floating toolbars are common in graphics applications so they can be moved into the canvas area near the objects being worked on. See tool palette
Most toolbar buttons display only icons such as these from VTEL's videoconferencing software. Some toolbars include text descriptions.
