Image captions and comments/bookmarks are formatted with two standard styles called Image Caption and Comment. These styles are applied automatically to all image captions and comments and they are the only styles that these elements can use.
This means that all image captions and all comments/bookmarks in your project will have the same style. You can override these styles and change the formatting of individual captions and comments by applying manual formatting.
If you manage multiple projects that all need to look the same, check out Help+Manual's powerful style repositories. They allow you to share stylesheets between multiple projects and edit the styles for all of them in the same central location. See the Working with Style Repositories chapter for details!
•The Image Caption and Comment styles only have font attributes. If you set paragraph attributes in the style definition they will be ignored.
•All the text in captions and comments has same font attributes. You cannot format individual words differently from the rest of the text.
•Image captions are always centered, comments are always left-aligned. Since the styles do not have paragraph attributes you cannot change these settings.
Select Styles > Edit Styles in the Write tab, then select the Comment or Image Caption style in the list and edit its font attributes. (Don't bother editing the paragraph, border or background attributes because these are ignored for these styles.
•See Editing styles for more information.
You can also change the formatting of individual captions and comments manually:
•Just click on the graphic or comment in the editor to select it, then select the font attribute you want to apply (bold, underlined, font etc).
All formatting will be applied to the entire comment or caption text. You cannot apply different formatting to parts of the text. Also remember that you cannot apply paragraph attributes to these texts, they will simply be ignored.
