Step-by-step explanation:
True, a task pane can indeed remain open while you are working in a document. In many software applications, especially in Office suites like Microsoft Office, the task pane is designed to provide quick access to commonly used functions and tools, such as clip art, shapes, document formatting, and more, without interrupting the workflow on the main document area. You can perform actions in the task pane while simultaneously editing your document, and since it is often docked to the side of the application window, it allows for easy multitasking.
