Test your mechanical keyboard, laptop keyboard, and custom macro pads instantly from a convenient popup, without ever needing to open a new tab or search for a testing website. 【 ✨ FEATURES 】 - Instant Recognition: Open the popup and start pressing keys! They will instantly map to the on-screen 60% visualizer grid. - NKRO (N-Key Rollover): See exactly how many keys your keyboard can register simultaneously. Detects if you have true Full N-key Rollover or a cheaper 6-Key limit. - CPS (Clicks Per Second): Test your raw typing or butterfly-clicking speed with customized time trials (5s, 10s, 30s). - Physical Diagnostics: Built-in safeguards like double-click/chatter detection (< 30ms) and hardware drop-off testing to catch faulty switches. - Real-Time Visuals: See your last pressed key highlighted prominently with zero latency. - Always Accessible: Works seamlessly from your Chrome toolbar, whether you're on Windows, Mac, or ChromeOS. 【 🕹️ HOW TO USE 】 1.
