Some scripts may use the term INTERCUT BETWEEN. At this point, two scenes will be shown a few moments each, back and forth. For example, if Laura is stuck in her flaming house and the fire department in on the way, a screenplay may call for intercutting between the flames closing in on Laura and the fire fighters riding across town to save her.
Note: this is a style that can be written around with standard scene breaks. It's more to prepare the reader for the upcoming slug line bonanza.
