About the test

Built for mechanical-keyboard DIYers, repair checks, and quick browser input testing. Duplicate modifier keys are detected separately, and hovering a key reveals its KeyboardEvent.code.

Why do labels differ from what I type?

This tester checks physical scan-code positions. For example, the key beside Tab is reported as KeyQ even when an AZERTY locale makes it type “A”. Locale and character mapping are outside the scope of a hardware key test.

Why is a key not detected?

Browsers and operating systems reserve some shortcuts and media keys. F11, Print Screen, Meta, and similar keys may be captured before the page receives them. Trying a modifier combination or another browser can help.

Browser and platform support

The tester supports current Chrome, Safari, Firefox, and Edge releases on Windows, macOS, Linux, and Android. A few platform-specific keys can report equivalent codes; the tester normalizes common cases such as Print Screen/F13 and Help/Insert.
