Test Your Touchpad, Keyboard & Mouse

Pick a device below. Every keypress, click, scroll, and gesture lights up live so you can see exactly what your hardware is (and isn't) sending to the browser.

Try: move the cursor · single click · right-click (two-finger tap on Mac) · double-click · click-and-drag · two-finger scroll · pinch to zoom

What you've typed
Press any key on your physical keyboard — it lights up here labeled for the layout you picked, so you can confirm the right character reaches the browser. Keys you've already pressed stay green so you can see what's left to check; press them again any time. The fn key is dimmed because macOS and most laptop firmware handle it before the browser ever sees it.

Click anywhere in this area with left, right, and middle buttons, scroll the wheel, drag, and — if your mouse has them — press the thumb side buttons.

Side buttons only work on mice that have them (common on gaming and productivity mice).
