Your key presses stay in your browser. Some operating-system shortcuts, the Fn key and certain media keys cannot be reported by browsers. The displayed layout is based on a standard US keyboard.
Check keys together
Hold Shift, Ctrl or Alt while pressing other keys. The tester highlights simultaneous key presses when your operating system forwards them to the browser.
Check your mouse
Move your pointer over the mouse test area and try left-click, right-click, middle-click and scrolling to see their status.

Keyboard tester FAQs
How can I tell whether a keyboard key is working?
Press the physical key while this page is open. Its on-screen key should light up and its name should appear in the status panel. If nothing happens, try focusing the test area and check the key in another application.
Why don't some keys show up?
Some keys, such as Fn, brightness controls, or system shortcuts, are handled by the device or operating system and may never reach the browser. This does not necessarily indicate a keyboard fault.
Can I test my keyboard without installing software?
Yes. The tester runs in your browser using standard keyboard and mouse events. You do not need to download an app or create an account.
Does this test work for Mac and Windows keyboards?
Yes. Choose Windows or Mac to change modifier-key labels. The tester reads the physical keyboard codes the browser reports; some special-key behaviors vary by browser and operating system.
Can this tool diagnose a broken keyboard?
It can show whether the browser receives a key press, helping identify possible problems. It cannot reliably identify the underlying hardware cause, and system shortcuts or language layouts can affect results.
