Screen shots won't be necessary. I got it to work by creating a new, test document containing a text box, with "Show Special Characters" activated. When I started typing, the special characters (e.g., line feeds and spaces) magically displayed. I also used a relatively large type size (16 pt.). Otherwise, the special characters are very difficult to see, at least on my iMac's 4.5K display. Unlike with Microsoft Office apps, the special characters in APub display smaller than the type size and in a faint blue color, at least on my monitor. Anyhow, thanks for your help, Walt. Much appreciated.
