Test every key on your keyboard with a visual layout that highlights each key as you press it. See the key name, event code, keyCode, which value, location (left vs right modifier), and whether it was a repeat event — all in real time.
Key Features
Visual keyboard layout
A full QWERTY keyboard rendered as clickable divs lights up each key as you press it. Wide keys (Shift, Enter, Space, etc.) are correctly proportioned.
Real-time key info panel
Displays key, code, keyCode, which, location (Standard / Left / Right / Numpad), and repeat status for the most recently pressed key.
Key history log
A running list of the last 20 unique keys pressed appears below the keyboard for easy reference.
No typing interference
All keydown events are preventDefault'd so pressing keys does not trigger browser shortcuts or scroll the page during testing.
