What key do you hold to mirror an output destination in the Output pop-up menu?

• A. Hold Control
• B. Hold Option
• C. Hold Shift
• D. Hold Command

Answer: (A)

Holding the Control key while you select an output in the Output pop-up is what mirrors that destination to all related outputs. This lets the same signal be routed to multiple outputs at once, saving you from choosing each one individually. The mirroring only happens while you’re holding Control, so releasing the key returns to choosing a single output. Other modifier keys don’t perform this mirroring behavior.
