Moving a footnote from one location to another.
If you add a footnote or endnote in one location and then decide it should be in another location, you don't need to delete it and start over again. Just move it by selecting the note reference mark in the body of the document and drag it to the new location. The note text arrives in the new destination as well.
Or perhaps you're using the same source again in another note. You can copy a note by selecting the note reference mark, holding down CTRL, and then dragging the mark to the new location. Word will automatically renumber the new note reference mark in the new location.
Tip If you need to revise anything in the copied note, such as the page number of the reference, just double-click the note reference mark in the body of the document. The insertion point moves directly to the note text so that you can make revisions.
