A question here should be self-contained. A form like “Tell me how to implement AMA §5 rule 9” is disrespectful for the benevolent contributors of this site. You should describe in simple words what you want to achieve. Remember that the majority of us are not 1) American, 2) English-speaking natives, 3) professional typographers.
There are two ways to answer your question, considering its ambiguity.
##Using existing footnote reference numbers
The same footnote may be referenced from several locations in your document:
Lorem² ipsum dolor² sit amet,
You create the footnote “as usual” on the first occurrence. The second reference is handled as a cross-reference:
Cross-references tab where you choose Type as Footnotes, select the correct note in Selection and Reference in Insert reference to. Of course, the inserted reference is formatted as ordinary text of the paragraph and should receive Footnote Anchor character style to look like a note reference.
If you customised
Footnotes & Endnotes, use the character style defined in Text Area instead of Footnote Anchor.
##Creating several footnotes at the same location and omitting some
Start by creating the notes as usual:
Lorem1,2,3,4 ipsum dolor sit amet,
Note I inserted commas between the note anchors. The commas are formatted as requested by the paragraph style. Apply character style Footnote anchor to make them look the same as the note references.
Now, you don’t like the sequence “1,2,3,4”. You want it to look like “1-4”. Remove the commas (they are plain text you added) and insert a dash before the “4” to get “123-4”. Assuming the dash has been styled, the line looks like:
Lorem123-4 ipsum dolor sit amet,
Create a new character style Hidden with Hidden attribute checked in
Font Effects (no other attribute needed). Select the “2” and “3” references and apply the Hidden character style. You get:
Lorem1-4 ipsum dolor sit amet,
Both techniques can be combined for non consecutive lists of note references. When the notes are created “inline”, the references are consecutive. Therefore something like “1,3-8,19” means only 19 may be a fresh note; all others are cross-references.
Important: when using such tricks as cross-references and hidden text, it is highly recommended to work with
Field Shadings enabled and to have Hidden text checked in Display fields of
(edit only removed typos; nothing new)
