General feedback

Email contact@mycelgrid.com about Computer Keyboard Test behavior, an unclear instruction or an accessibility problem.

Useful details include your browser name/version, operating system, selected diagram, the physical key or combination you tried, and what you expected versus what the page showed. A key intercepted by your operating system may not reach the browser; the manual explains that boundary.

Do not send passwords or a private typed passage. Start with non-sensitive reproduction steps. A downloaded report can reveal aggregate reference-key usage; include one only if it helps and you are comfortable sharing it. This app does not automatically upload reports or send test data with an email link.

Before you write

Confirm that the test area is active and focused, release the key and try again. Check the reference diagram and Outside this diagram list. For a numpad, consider Num Lock; for Fn/media shortcuts, compare another application or device. We cannot diagnose hardware or guarantee repair from a browser observation.
