Markdown Footnote

Posted by @pdavisonreiber, Last update over 1 year ago

Insert Markdown footnote [^1] in the text and add [^1]: at the end of the document. If there is text selected, move it to the footnote at the end of the document. Numbers used for references automatically increment each time.

Steps

  • script

    /* 
    If no text is selected:
    - add footnote [^1] at current cursor position
    - add reference [^1]: at end of document
    - move cursor to after reference [^1]: for text entry
    
    If text is selected:
    - replace selection with [^1]
    - add reference [^1]: at end of document, followed by selected text
    - move cursor to after [^1] in the body of the text
    
    Script automatically increments reference number for each new footnote.
