What document feature does using headings in 'Google Workspace: Docs - Part 1' help create?

Using headings in 'Google Workspace: Docs - Part 1' primarily aids in the creation of a table of contents. Headings are hierarchical text styles that signify the structure of a document, allowing readers to navigate easily to different sections. When headings are applied correctly, they can automatically be picked up by Google Docs to generate a table of contents, making it easy to organize and access various parts of the document.

This feature streamlines the reader's experience, especially in longer documents, by providing a quick reference guide to the content's organization. In contrast, while summaries, citations, and bibliographies are important elements of document formatting, they do not directly benefit from the heading structure in the same way that a table of contents does. A summary encapsulates the main points of the document, citations reference sourced material, and a bibliography lists the works consulted, but none of these features rely on the use of headings for their format or functionality.
