During text editing, you can enable a special 'protect' editing mode. When this mode is enabled, in the source editing window with hidden tags or in the WYSIWYG window, it is no longer possible to delete end of paragraphs and paragraph styles and their associated bells. This is useful when editing headlines.

See Protect tags and new paragraphs against deleting for more information.
