The initial footnote number is randomized and then sequence with any additional footnotes. This was used to fix a problem with using footnotes in Markdown files on Pelican static websites.

Fixed error where initial footnote did not include ‘:’

Another variation of two different footnote actions @pdavisonreiber‘s Markdown Footnote Action and David Blue’s variation

This version will insert the footnote marker at the point of markdown text and append the footnote marker at the end of the draft note ready for the user to enter the footnote text.

Steps

  • script

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