# Split Book Screen

By changing the screen layout of the book, it is possible to split the book screen into multiple panes. By placing sheets in each area, it becomes possible to work with sheets at the same time on the screen.

Follow the procedure below to split screen of the book.

1. Click the book menu in the book header or the book menu in the navigation menu and select "Settings".
2. Click "Layout" tab in the "Change Book Settings" dialog, and then select a layout with multiple pane areas from "Pane Layout" pulldown.

By dragging and dropping the sheet tabs to the splitted pane areas, or clicking the "Add new sheet" link in each pane area, you can move or add sheets to the pane areas.

If the layout of the book is changed to the one with fewer areas, all the sheets shown in the reduced area are added to the first area.
