Hi, thanks for the response.

I tried using this find and request command but it made 0 replacements. To clarify I put [\(\)] in the find box and nothing in the replace box. I went into format/font and ticked superscipt in the find box. I then tried ticking "use wildcards" but this also failed to make any changes.

Is it possible that I am doing this incorrectly somehow? The footnote numbers are superscript numbers, but they are also linked footnote references. When I hover over the numbers they show a little box with the footnote text. I'm not sure if this makes a difference to the type of command needed?
