In the bottom-right corner of the notebook are the page buttons. These buttons let you bring one page of the notebook into view at a time. They are a standard component that is automatically provided with every old notebook. However, the application can change the default width and height of the page buttons by using the BKM_SETDIMENSIONS message. The page buttons always are located in the corner where the recessed edges of the notebook intersect.
Selecting the forward page button (the arrow pointing to the right) causes the next page to be displayed and selecting the backward page button (the arrow pointing to the left) causes the previous page to be displayed. Prior to inserting pages in the notebook, the page buttons are displayed with unavailable-state emphasis; therefore, selecting either page button would not bring a page into view.
