What is how to insert a footnote in word?

Here's how to insert a footnote in Microsoft Word:

To insert a footnote, go to the References tab on the ribbon. In the "Footnotes" group, click the "Insert Footnote" button. This will insert a footnote number at your cursor location in the main text and take you to the footnote area at the bottom of the page, where you can type your footnote text. You can also use the keyboard shortcut Ctrl + Alt + F to achieve the same result.

You can customize your Footnote%20Options by clicking the small arrow in the lower-right corner of the "Footnotes" group on the References tab. This opens the "Footnote and Endnote" dialog box, where you can change the number format, starting number, and other options. You can also choose to convert footnotes to endnotes, and vice versa.
