You can select text, then drag it to another location. You can drop the text at a different location in the same window or in another one.
Dragging text moves it to the new location. To copy it to a new location, hold down the Ctrl key while dragging the text: the cursor changes to indicate a copy operation. Press the Esc key while dragging text to cancel the drag-and-drop edit.
By default, drag-and drop-editing is disabled and you must enable it if you want to use it.
