It contains a set of icons or buttons that provide quick access to commonly used functions or tools, making it easier for users to navigate and perform tasks efficiently. Toolbars can be customized to suit individual preferences and can include options such as file management, formatting, and editing tools. They serve as a convenient and time-saving feature for users, allowing them to complete tasks with just a few clicks.
