Final answer:
The option under the Table of Contents for automatically including text formatted with Heading 1-3 Styles in a document is known as Automatic Table 1 or Automatic Table 2. These features facilitate document navigation and are handy in academic settings.
Step-by-step explanation:
The built-in option under the Table of Contents that allows the user to add an automatic table including all text formatted with the Heading 1-3 Styles is typically referred to as Automatic Table 1 or Automatic Table 2. These options are designed to streamline the creation of a table of contents in a document, making it much more convenient for navigation in both digital and print formats. Users can quickly click through different sections and subsections of a document thanks to this feature, which proves exceedingly useful in classroom settings where students and professors need to be on the same page, figuratively and literally.
On a computer, the table of contents will generally be displayed in the upper right-hand corner of the page, while on a mobile device, it will appear at the top of each page. Digital navigation is enhanced with features like collapsible subsections and 'breadcrumbs' for ease of movement through the document. These aspects of a digital Table of Contents benefit readers by providing an organized and efficient way to access various parts of the text, whether it's for casual reading or rigorous academic study.
