Keyboard tester
Test physical keys, left/right modifiers, navigation keys, and the numpad. See simultaneous-key counts, lock states, repeats, and a downloadable report.

Start the test, then press keys and combinations.
Layouts show physical codes, not a language map. Location 1/2 identifies left/right modifiers; 3 identifies the numpad. Lock states are the last browser-reported values. Browser and operating-system shortcuts may never reach this page.
Three small steps.
- Click Start keyboard test to focus the test area.
- Press keys and combinations, then inspect the received event details.
- Click Stop or move focus away to end the test.
A few things to know.
ANSI/ISO diagrams represent physical codes, not a language layout. Lock states are last observed event values. Browsers and operating systems reserve some shortcuts; Fn and hardware keys may not produce events. This cannot prove that every switch is physically healthy. Reports aggregate only events inside the focused test area.
How your privacy works →A little more clarity.
Why is Fn not lighting up?
Many keyboards handle Fn internally and never send it to the browser. Its absence here does not establish a hardware fault.
Are keystrokes tracked elsewhere?
No. Key listeners are limited to the active test area. Events are not sent to analytics or automatically saved to disk. A report is saved only when you choose to download it.
