The selectable cooking modes an enclosed-cavity oven offers, by heating pattern and intent: bake (both elements, even heat), broil / grill (top element, surface browning), toast (cycle the elements like a toaster), convection (a fan circulates the hot air for faster, more even cooking), air fry (high-speed convection with a perforated basket for crisping with little oil), roast, reheat, keep warm, proof (gentle warmth for dough), and dehydrate (low heat over a long time). A token category recurring across toaster ovens, countertop ovens and air-fryer ovens (L11); a model offers several; growing (L13).
