When you first set up a project, some styles are mapped automatically. If the FrameMaker style name exactly matches a WebWorks Publisher style, the style is automapped. You can distinguish automapped styles from styles you have mapped-only automapped styles have an arrow in front of them.
There's no difference in function between an automapped style and a style that you map manually-they both convert content to the appropriate output. The output, however, typically won't be formatted correctly if the FrameMaker style was automatically mapped to Default. You need to manually map those styles.
In addition to the "identical names" rule, some styles are automapped even though the names don't match. For example, the Body paragraph style is automatically mapped to Body in the HTML template. Imported graphics are automapped based on their file type and on whether the anchored frame contains additional content (such as callouts).
The default set of FrameMaker markers is automapped in WebWorks Publisher, so hypertext, cross-references, and footnotes are all converted automatically.
