Controlling scenes while live streaming (e.g. live / "AFK" / switch to "I'm dead" mode during multiplayer live stream / ...) is the most common use case for this type of keyboard I'm aware of. It's much less error prone than pressing a shortcut since it's a single button press. One of the most common commercial product for this particular use case is Elgato Stream Deck.
