11.6 Creating Footnotes
A footnote is defined in a paragraph that is started by a footnote marker in square brackets in column 0, no indentation allowed. The footnote reference is simply the marker in square brackets, inside text. For example:
The Org website[fn:1] now looks a lot better than it used to.
...
[fn:1] The link is: https://orgmode.org
The following commands handle footnotes:
C-c C-x f (org-footnote-action)
The footnote action command. When point is on a footnote reference, jump to the definition. When it is at a definition, jump to the (first) reference. Otherwise, create a new footnote. When this command is called with a prefix argument, a menu of additional options including renumbering is offered.
C-c C-c (org-ctrl-c-ctrl-c)
Jump between definition and reference.
