Load button 10.Save button 11.Menu item "?" 12.Back button 13.Combobox in the navigation area 14.Forward button All other dialog elements should not act as a tab stop. Please note that in JavaFX the so-called "TraversalEngine" takes care of focusing the elements of a layout. Normally the elements are in their internal order iterate (order in which the containers were added). If you want to change the order you can create the desired order in your fxml file, a Use event filters (trap the tab key and set focus manually) or implement your own traversal engine (use internal API by deriving from com.sun.javafx.scene.traversal.TraversalEngine).
