Inserting a Footnote
Click in your document where you want to place the anchor of the note.
From the Insert menu, choose Footnote.
In the Numbering section, select the format you want to use. If you are using automatic graphics captions and you chose to number the footnotes, footnotes will not automatically be updated when new footnotes are inserted. To work around this, you can use a special character instead of a number. Select the Character option and either type the character you want to use or click the browse button (...) and select the character that you want to use for the footnote.
In the Type are, select Footnote.
Click OK.
Type the note in the footnote area on your page.
To switch between footnotes and anchors, click the reference for either the note or the anchor.
