Know what are markers in FrameMaker.
FrameMaker markers provide you multiple ways in which you can mark your documents. You can choose from pre-defined markers, such as Author, Comment, Conditional Tags, ContextString, Cross-Ref, Equation, Glossary; or create custom markers.
The Markers panel makes it easier to work with and troubleshoot hundreds of markers in a long document or book files. You can display all the markers in the current document, all open documents, selected file, or a book.
