I’m transcribing a flyer, so I haven’t set up a formal special symbols page. There’s an asterisk and I’m defining it in a 7-5 TN. However, to define the asterisk, I need the dot locator for mention–which requires explanation, itself, doesn’t it? So, do I need to set up a special symbols page because now I have two symbols to define?
Maybe consider using an embedded transcribers note with the word “asterisk” after the symbol. That way you don’t need the dot locator. If that won’t work, then yes, do a “symbols used below…” TN.
