Comment Styles and Custom Languages
When you define a custom language, using the Preferences: Languages dialog box, you can specify comment or text-range types, and associate them with a style. For example, you could create a comment range that starts with (* and ends with *) and the text is formatted with the “Comment Multi Line” style. You can actually define any delimited range of text, and associate it with any style (including a non-comment style). For more information, see “Programming Languages”, and “Special Language Options”.
