Smoke, a suspicion of smoke, fumes or serious suspicion thereof, regardless of the route cause may lead to a crew actioning a generic checklist labelled “smoke, fire or fumes”...and potentially lead to a diversion

As others have now pointed out actioning a “smoke ...checklist” doesn’t automatically mean the crew were dealing with clouds of visible combustion products that will leave traces all over the flight deck.
