A toolbar is a horizontal bar, usually located at the top or bottom of a computer screen, that contains buttons and icons which provide access to various functions and features. In the context of web browsers, it refers specifically to the row of clickable icons that appear along the top edge of the browser window, providing quick access to common actions such as browsing backward or forward, refreshing the page, searching, printing, or accessing bookmarks. Toolbars can also be found in other software applications, such as word processors or image editors, where they provide similar functionality for specific tasks within that program.
