What is a text box used for in document editing?

A text box serves as a designated area within a document for holding and displaying text. This tool is particularly useful in document editing as it allows users to place text precisely where they want it on the page, separate from the main body of text. It can be used for various purposes, including annotations, sidebars, or isolating text visually for emphasis.

While other options describe functionalities that are relevant in document editing, they do not accurately define the primary role of a text box. For instance, hyperlinks, video embedding, and applying styles relate to different aspects of document manipulation rather than how a text box operates in terms of holding text.
