NKRO (N-Key Rollover): The maximum number of keys that a keyboard can simultaneously recognize

Gaming Impact: Anti-ghosting performance directly affects multi-key operation experience in games

Mechanical Keyboards: Usually have better anti-ghosting performance than membrane keyboards

Test Significance: Helps you understand keyboard reliability in high-intensity usage scenarios

⚠️ Hardware Limitations

USB HID Protocol: Standard USB keyboards support maximum 6 simultaneous regular keys

Keyboard Hardware: Regular keyboards support 6KRO, high-end gaming keyboards may support 10-key or full NKRO

Browser Environment: May have additional limitations on simultaneous key detection
