Footnotes and endnotes

Hi all,
How do I add footnotes and endnotes?
I tried ‘Format’ ‘Footnote’, but I don’t really understand it.
Thanks in advance.

With your cursor at the place where you want the marker added, go to the commands in the ‘Insert’ menu. There are also short-cuts listed.

You can add footnote icons to the toolbar also, for both inline and inspector footnotes.

Do you want to add both in the same document? If so, have a look at this thread:
