How to see indexed words in text copy

I indexed a book in 2015. I am returned to the index now as we are translating the book. I remember being able to see indexed terms in the actual text of the book. Now I am only able to see the blue carrot (upside down v) that denotes where an index term resides, but it does not actually show what word or phrase is being referenced at that point. I realize that I can see the indexed words in the index pane. However, it was so useful to see it right inline with the text copy. Is there a toggle I am not seeing that would allow me to see what terms are where. Or do I just need to get used to working in the index menu? Thanks for your help!
