Goodnotes: Writing with the Zoom Window
1. You can write on the Zoom window with your large finger or stylus. The window at the bottom magnifies a part of the page which corresponds to the blue box on the page.
2. Writing in this area will automatically move the blue box on the page forward.
3. You can resize the Zoom box on the page. The smaller the box, the higher the magnification level of the Zoom window.
