For any content that appears in the Reading panel, you can select it (by right-clicking) to call up Bookmark | Highlight | Add a Note <Fig. 1>. Selecting one of these actions allows you to bookmark an entire section, highlight the selected content, or attach a note to a paragraph.
If you select Add a Note, you’ll be presented with another dialog box that will allow you to type in a note, select an existing folder in which to save it, or create a new folder in which to save it. You can always access your saved notes from My Content on the Home Page.
