How do I create footnotes or endnotes?

 

Add footnotes or chapter endnotes using the footnote shortcode

You can add a footnote or endnote as follows in either the TEXT editor, OR the VISUAL editor:

This will automatically create a footnote (or endnote) with the text inside the [[footnote][/footnote]] "shortcode". You can achieve the same thing using the footnote button in the VISUAL editor, by placing your cursor where you want your footnote marker to appear, selecting the "FN" button and adding your footnote text.
