FAQ
How do I test my keyboard?
Click the keyboard picture, then press every key. Keys that work turn pink; the one you are holding turns dark.
A key does not light up. Is it broken?
Not always. Fn, some media keys and keys the system reserves (like Print Screen on some computers) never reach the browser. Try the key in a text field too.
What is key rollover?
How many keys the keyboard reports at once. Hold several keys together; “Most at once” shows the highest number seen.
What do key, code and keyCode mean?
key is the character or name the key produces, code is the physical key position, and keyCode is the older numeric code many games still use.
Is anything recorded?
No. Key presses are shown in this tab only and are not sent anywhere.
