Text of this guide (for searching): Books: Working with Layers of Objects. Open a Book from Supplies.
Everything is an Object. You can open Halos and use the handles, menus, and script tiles for any thing. Right click in the middle of your book to open the book's halo and then, in the same place, right click again to open the page's halo.
Right click on your book's top border icons and find Halo handles for: Alignment, Page Controls, and
ThreePhaseButton.
Open Viewers and experiment with script tiles and menus. Put an ellipse in your book; the ellipse is on a page and the page is in a book.
Try: open a halo for the book, the page, and the ellipse.
Read the labels so you know which layer's halo you have selected.
Change things using halo handles for the book, the page, and the ellipse. frog traced image from www.free-nature-photos.org. You decide what options will be best for your projects.
