Entire XML elements can be moved or copied in the edited document using only the mouse in the Outliner view in drag-and-drop operations. If you drag an XML element in the Outliner view and drop it on another one in the same panel then the dragged element will be moved after the drop target element. If you hold the mouse pointer over the drop target for a short time before the drop then the drop element will be expanded first and the dragged element will be moved inside the drop one after its opening tag. If you hold down the CTRL key it will be performed a copy operation instead a move one.
The drag and drop action in the Outliner view can be disabled and reenabled from the Preferences dialog.
The Add Child, Insert - Before and Insert - After submenus of the outline tree popup menu allow to quickly insert new tags in the document at the place of the element currectly selected in the Outline tree. The Add Child submenu lists the names of all the elements which are allowed by the schema associated with the current document as child of the current element. The effect is the same as typing the '<' character and selecting an element name from the popup menu offered by the content completion assistant. The Insert - Before and Insert - After submenus of the Outline tree popup menu list the elements which are allowed by the schema associated with the current document as siblings of the current element inserted immediately before respectively after the current element.
The Toggle comment item of the outline tree popup menu is the same item as in the editor popup menu with the same name. It encloses the currently selected element of the outline tree in an XML comment, if the element is not commented, or uncomments it if it is commented.
The Cut, Copy and Delete items of the popup menu execute the same actions as the Edit menu items with the same name on the elements currently selected in the outline tree.
