FAQ
How do I know if a key is working? ▼
Press the key — it turns red (Active) while held. Release it and it turns green (Tested), confirming detection. A key staying dark after pressing may be unresponsive or damaged.
What's the difference between keyboard sizes? ▼
60% is just the core alphanumeric keys — compact and portable. 65% adds a right-side column with arrow keys and Delete. 75% adds the function row (F1–F12). TKL is full-size minus the numpad. 100% includes everything including the numpad.
What is keyboard ghosting? ▼
Ghosting occurs when a keyboard fails to register certain key combinations — typically when 3+ keys are pressed simultaneously. Redragon mechanical keyboards support N-Key Rollover (NKRO), registering every key no matter how many are held at once.
What is N-Key Rollover (NKRO)? ▼
N-Key Rollover means every key press is independently detected even when all keys are held simultaneously. Critical for fast-paced gaming. Most Redragon keyboards support full NKRO over USB.
Why isn't the tester detecting my keys? ▼
Most likely the page doesn't have browser focus. Click anywhere on the page first, then try again. Browser extensions that capture keyboard shortcuts may also interfere — try disabling them temporarily.
My Redragon keyboard has an unresponsive key — what should I do? ▼
Use this tester to confirm which key is failing. Check if the switch is hot-swappable (most Redragon boards support this) and reseat it. Check Redragon software for remapped keys. If the issue persists, contact Redragon support — all keyboards include a manufacturer warranty.
