Thanks for your efforts, and let me add my Amen to both
subjects (on file locations and on Character styles).
My real-world use of Character styles is a combination usage
of Paragraph and Character styles for Notes: I have a Paragraph
style called Note, which simply adds margins of .15in Left, 10pt
Top, and 8pt Bottom. Within this paragraph style, multiple labels
announce the type of Note with the use of Character styles
NoteLabel (Navy), RecommendLabel (Teal), CAUTIONLabel (Purple), and
This way, you can change the color of one or more labels
without worrying about the paragraph settings (or vice versa).
Also, when placing a Note inside a table cell (which might
have limited horizontal space, especially with three or four
columns), we still use the "Label" character styles but
without the Notes paragraph style. This still sets off the
text visually, without adding unnecessary extra vertical space.
