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. When a  field or  tag depends on another field or tag it is regarded as a "child" of its "parent" field or tag. Parent field and tags are denoted by a folder icon which may be "opened" to  display its children or "closed" to  conceal them. Clicking a field, tag or parent name selects it; right-clicking opens a pop-up menu.
| • | To show the contents of a parent folder, double-click its folder icon or
select Expand from the pop-up menu. |
| • | To hide the contents of a parent folder, double-click its folder icon or
select Collapse from the pop-up menu. |
| • | To make a field or tag dependent on another (parent) field or tag, click down on the (child's) name and drag it onto the parent name. The parent folder icon replaces the field or tag icon when the mouse button is released. |
| • | To 'promote' an existing field or tag out of a parent folder, click down on the field or tag icon and drag it onto the icon of the field or tag that it should follow. (If all the child fields/tags have been promoted out of a parent folder, the parent icon reverts to its native field or tag icon.) |
| • | To delete a field, tag, or parent folder and its sub-fields, press Delete key or
select Delete from the pop-up menu.
A warning dialog appears when deleting parent folders: click |
| o | Yes to delete the folder and its sub-fields or |
| o | No to cancel the command. To delete the parent field or tag but not its sub-fields, move the sub-fields out of the folder first. |
|
Right-clicking a field or tag selects it and displays the pop-up menu:
| • | Move up or Ctrl U: steps the selected field or tag up the list. |
| • | Move down or Ctrl D: steps the selected field or tag down the list. |
| • | New field or Ctrl N: creates a new field as a child of the clicked field; see also To define a field. |
| • | Combine with next field or Ctrl C: expands the selected field, tag or parent to encompass and override the next field, tag or parent in the list at the same level or lower. |
| • | Combine selected fields: all selected fields are combined into the selected field which is highest in the list/tree. |
| o | To select a group of fields, click in the highest field to be selected then hold down the Shift key and click the lowest field to be selected. |
| o | To add a field to the current selected file(s), hold down the Ctrl key and click the field to be added. |

To move the list/tree window
The list/tree window may be docked on the right of the tabbed-pages window or below it.
| 1. | Use the mouse to drag the border of the dialog so that it is big enough to hold the list/tree window in its new position. |
| 2. | Click the mouse button down in the list/tree window (without selecting a field or tag), drag the window to the new location then release the mouse button. |
| 3. | Adjust the dialog border(s) for best fit. |
