\footnotemark
-------------
The `\footnotemark' command puts the footnote `number' in the text.
This command can be used in inner paragraph mode. The text of the
footnote is supplied by the `\footnotetext' command.
This command can be used to produce several consecutive footnote
markers referring to the same footnote by using
`\footnotemark[\value{footnote}]'
after the first `\footnote' command.
