Found a wrong key, a layout that does not match your keyboard or a result that looks odd? Write to us.

What to include in a bug report
A short message with these details is enough to reproduce most problems:
- The page you used, for example the keyboard test or the ghosting test.
- Your browser and operating system, for example Chrome on Windows 11 or Safari on macOS.
- The keyboard model and layout, for example a laptop with a German QWERTZ layout, or a 75% mechanical board.
- Which key or position looks wrong, and what you expected to see.
- The text report from the test, if you saved one. It contains key positions and counts only, never what you typed.
Please do not send passwords or private text. The tool never needs them.

Layout requests, translation corrections, partnerships and sponsorship questions go to the same address. Say in the subject line what the message is about.
For how the test works and what a browser cannot see, read the methodology first; many unexpected results are explained there, for example why Fn and some media keys never reach a web page.
