Organizing Pages Using Divider Pages   A Divider page marks the start of a section within a Notebook.  It lists the pages that live within its section in the form of an outline.  Outlines are great for managing lists, and especially hierarchical lists, such as pages and dividers organized into sections and subsections.     Adding Pages to a Divider When you’re turned to a Divider page, pressing Return with nothing selected adds a new Note page to the Divider.  If you’ve selected a page in the Divider’s outline, pressing Return adds a new page of that type right after the selected page. You can also add pages using the commands in the Page menu. Once you’ve added pages, you can reorder them by dragging, or by using the commands in the Outline → Move menu. Each page you add to a Notebook is owned by the Contents page or other Divider page. NOTE: By default Notebook adds a tab to each new Divider page.  You can change this behavior in the Notebook pane in the Inspector Window (Window → Inspector).     Creating a Subsection If you add a new Divider page (Page → Divider Page), the new Divider page marks the start of a subsection.  By moving Note and other pages to be children of the new Divider, those pages become part of the new subsection. When you add a page to a Divider, NoteBook shows that Divider with a triangle next to its name.  Clicking the triangle hides or shows the pages the Divider owns. You can continue adding new Divider pages to existing Dividers to create any number of sections and subsections, with any level of depth, within your Notebooks. Removing Pages Choosing Page → Delete deletes the current page.  If you’ve turned to a Divider page, pressing the Delete key deletes the pages you’ve selected in the outline.  Additionally, the Page → Remove Multidex removes the Notebook’s Multidex pages (you can add them back by choosing Page → Add Multidex).  You cannot delete the Contents page.
