Shift-dragging is one of the ways to control Editors.
How to Shift-drag
1. Position the mouse above any of the objects that you want to drag (the objects were probably selected first).
2. Press a Shift key.
3. Press the (left) mouse button.
4. Keeping the mouse button pressed, move the mouse across the window. A shadow of the objects will follow.
5. Release the mouse button when it is above the location where you want your objects to be moved. If this drop site makes any sense, the objects will move there.
