To incorporate Annotations into a Word document or Google doc, they must be added to a Note, which shows up in the right pane.
Click on the icon in the upper right corner for the Notes view. Then click on the plus symbol.
The Add Item Note choice opens a blank note. Type a note directly into the space OR drag and drop one or more annotations from the left pane into the blank note. To add all the annotations into a single note, choose the Add Item Note from Annotations option.
