Fields are listed in a window of the Field dialog, usually on the right-hand side of the window containing the tabbed field set-up pages (see also docking, below). The field-names can be shown as a simple list in alphabetical order (convenient for finding and editing) or in Tree view.

Tree view not only shows the order in which fields are output (for example, for CSV export) but also how the fields relate to each other.
