If you stand still for a second, a little button will appear in the top right-hand corner that says "Menu". And the same goes for the camera that you can normally zoom in by pushing "L". If you wait a sec, you can zoom in with the little camera icon in the top left corner. And also, the same goes for talking to a guest following you around. If you stand still for a sec, you'll see a little talking balloon thing in the bottom right corner.
