Footnote or endnote reference marks appear as 1,2,3... by default. Word provides you with various options in order to customize the reference marks the way you wish. If you’d like to change your footnotes or endnotes to be a,b,c or Roman numerals i, ii, iii, you can do that through the Insert menu. You can format the location of the footnote or endnote to be at the bottom of the text, or at the bottom of the page. You can also have Word renumber your footnotes or endnotes after each section of your document, and change the font and other formatting for a reference mark. You format a footnote or endnote reference mark in the same way you format any other text in a document.
