toolbar definition by American Heritage Dictionary
toolbar - Computer Definition
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 be allowed to float. For example, floating toolbars are common in graphics applications so that they can be moved into the canvas area near the objects being worked on. See tool palette, tool and toolkit.
