Help+Manual's dynamic styles are defined and edited by selecting Styles > Edit Styles in the Write tab. The style at the cursor position is automatically selected for editing.
If you have not used dynamic styles in a word processor before please study the chapter on Dynamic Styles in the Reference section before proceeding. This will make using styles much easier for you.
Help and Print style settings: You can define two different sets of attributes for every style: One for electronic help formats (HTML Help, WebHelp, Visual Studio Help and eBooks) and one for print-style output (PDF, printed manuals and Word DOCX). See Help and print styles for more details on this.
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!
