How to code sub-choices?

I was using a character customization template and while testing the story I noticed that to go to the next page of, say, hair colors there were tiney arrow like bubbles beneath the normal, large rectangular choices that said “next” and “back” and “last” to get me to the next or previous page of styles or all the way back to the main page. How do you code these in?
