FAQ

Common questions

Do I need to install anything?

No. Everything runs directly in your browser. Open the page and start pressing keys.

Can this detect hardware issues?

It can reveal symptoms such as dead keys, unstable repeats, missing combinations and uneven input timing. It does not replace electrical lab testing.

Does it work on laptops and external keyboards?

Yes. It works with most laptop keyboards, USB keyboards and many wireless keyboards supported by the browser and operating system.

Why do some labels differ from my physical keyboard?

Physical legends, browser events and operating system layouts can differ. The tool shows what the browser actually receives.
