Which feature allows you to customize how footnotes appear in a document?

The feature that allows you to customize how footnotes appear in a document is found within the footnote options in the menu. This specific area provides various settings that enable users to adjust aspects such as the numbering format, the position of the footnotes (whether at the bottom of the page or at the end of the document), and the layout style. This level of customization is essential for ensuring that footnotes align with the specific formatting requirements of a document or personal preferences.

While style settings also influence the overall appearance of text, including footnotes, they do not provide the same targeted customization specific to footnotes. Text formatting tools apply to general formatting adjustments, such as font size or color, rather than footnote-specific settings. Proofing options are primarily focused on checking spelling and grammar and do not play a role in customizing footnote appearances. Therefore, footnote options in the menu is the most accurate choice for this particular task.
