Hold real-world key combinations and watch whether your keyboard reports the combo cleanly or starts dropping keys in the browser.
Start testing combos
Try common multi-key combinations like W + A + Space or Q + W + E. This page helps you spot blocked or unreliable combo zones.
Frequently Asked Questions
How do I test keyboard ghosting? +
Hold the key combinations that fail in your game or app and watch whether extra keys appear or expected keys disappear. Common checks include W+A+Space, Shift+W+Space, and several number-row or modifier combinations.
Is keyboard ghosting a browser problem? +
Usually no. Ghosting comes from the keyboard matrix and rollover limits before the signal reaches the browser. Retest over USB and in another app; if the same combo fails, the keyboard hardware is the likely limit.
Do I need an NKRO keyboard? +
You need NKRO only if your real shortcuts or game inputs fail on the current keyboard. If everyday combos work, a 6KRO keyboard can be fine; if critical combos drop repeatedly, NKRO is the cleaner replacement path.
