What is this tool?

This tool checks whether every key on your physical keyboard is being detected correctly by your browser and operating system. It is useful after buying a new or used keyboard, after a spill or repair, or when troubleshooting keys that seem unresponsive.

How to use it

Click on the page to give it focus, then press any key. The corresponding key on the on-screen layout highlights immediately, confirming the browser received the keypress.
  1. Open the page and click anywhere on it to ensure it has focus.|Press any key on your keyboard.|The matching key on the on-screen layout highlights if it was detected.|Press different keys, including modifiers like Shift and Ctrl, to check the full layout.

Example

Example: pressing the letter "A" highlights the "A" key on the on-screen layout; pressing Shift highlights both Shift keys shown on the layout.

How it works

The page listens for the browser's native `keydown` and `keyup` events, reads the key code reported by the operating system, and highlights the matching key element on the rendered on-screen keyboard. No calculation or external lookup is involved -- it is a direct, real-time mapping of physical key to on-screen key.

Common use cases

Checking a new or second-hand keyboard for dead or unresponsive keys.|Diagnosing a specific key after a spill, repair, or keycap replacement.|Verifying a laptop keyboard before selling or returning a device.|Testing a keyboard layout after switching keyboard language settings.

Benefits

Instant visual feedback with no software to install; works on any device with a physical keyboard and a browser; free and requires no signup.

Limitations

Some browser extensions, OS-level shortcuts, or remote-desktop/virtual-machine setups can intercept certain key combinations before they reach the browser, which may make a working key appear undetected here; special multimedia or vendor-specific keys may not be mapped on the on-screen layout.

Privacy & your data

Key presses are read directly in your browser using standard JavaScript keyboard events. Nothing you type is sent to the A2Z Tools server, logged, or stored.

Frequently asked questions

Why isn't a specific key highlighting?
If a key doesn't highlight, your browser or OS may not be receiving that keypress -- check for a hardware fault, a stuck key, or an OS-level shortcut/extension intercepting that key before it reaches the browser.
Does this tool work with laptop and external keyboards?
Yes. Any keyboard your operating system recognizes and sends key events for will work, including built-in laptop keyboards, USB keyboards, and Bluetooth keyboards.
Is my typing recorded or sent anywhere?
No. Key presses are processed locally in your browser using JavaScript keyboard events and are not sent to the A2Z Tools server or stored.
Does this tool fix unresponsive keys?
No, it only detects and displays which keys register a press. It cannot repair hardware issues; it simply helps you identify which key is affected.
