Question Author
As you rightly said, the HTML codes were removed from my message.
These were
an opening fleche sup close fleche, followed by the number of the footnote then,
open fleche - slash sup - close fleche.
What I'm looking for is a code (if it exists - it does it automatically in Word) to add before the first footnote, so that all subsequent ones are incremented by 1.
Some of the revisions include several extra footnotes and in a lengthy doc are difficult to spot. Highlighting these superscripts in colour helps to find and alter them, but they all revert to black every time a Save is done.
