Smart WindowingKeyCreator \ General-Interface \ Selection \ Smart-Windowing
When first entering a selection operation, there will be a Smart Windowing capability that is comparable to the Smart Selection. If you click and drag without first choosing a selection method, a WINDOW>ALL IN selection operation will be performed. A rubber band will be animated, as with normal Windowing operations. The Window will be closed (and the underlying entities selected) when you stop the mouse drag and release the mouse button.
