Font size of footnote number
The font of the footnote numbers in my documents has changed to a tiny size making it hard to read. Would you be able to advise on how to switch this back, as it had been fine up to now and I'm not sure which wrong button I've pressed. Many thanks.
Select one of the footnote symbols (take care to select only the symbol) and find the name of the style for that character. If it "normal", I don't have much advice for you. Click on the Styles drop-down, select "more" , find the style name that is associated with the footnote symbol, and edit the font format.
Be sure to save your document before doing any of this and do the manipulations on a copy of your working document.
