Punctuation Characters Under InDesign's Symbols Submenu
Bullet Character (•): Inserts a bullet point. Bullet characters are used in lists.
Copyright Symbol (©): Inserts a copyright symbol. Used to denote intellectual property.
Ellipsis (…): The ellipsis is the proper typographical symbol for the familiar "dot dot dot" you may be more used to typing. Use ellipses when denoting trailing thoughts…like so.
Paragraph Symbol (¶): Rarely used in day-to-day typesetting, the paragraph symbol marks a new paragraph. Proofreaders often use it when marking up copy.
Registered Trademark Symbol (®): Used to denote a term that's a registered trademark, such as Coca-Cola®. Looks a bit strange there doesn't it, a bit big? That's because the registered trademark symbol is usually made smaller and top-aligned with the rest of the type, or superscripted, like so: Coca-Cola®.
Section Symbol (§): Denotes a new section. Rarely used except as a decorative mark.
Trademark Symbol (™): The registered trademark's cousin, it denotes terms that are simply trademarked, like so: Google™.
