Quick answer
What Keyboard Layout Reference tells you
Compare common ANSI, ISO and JIS physical keyboard arrangements without changing your operating-system input language.
- Observed here
- ANSI, ISO and JIS physical references, Enter and left Shift shape differences, Additional JIS keys.
- How to interpret it
- The diagram is a layout reference, not automatic identification of your keyboard. Event highlights show what this browser receives even when the printed keycaps or operating-system layout differ.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Useful next comparison: Choose the matching reference, check the operating-system input language and compare key versus code for a key that seems misplaced.
Understanding the result
What a result means
The selected diagram compares physical ANSI, ISO and JIS shapes; it does not detect the keyboard attached to the computer. Enter shape, left Shift width and additional JIS positions are the most useful visual distinctions.
Confirm the pattern by repeating ansi, iso and jis physical references. Results reflect events and values exposed by this browser.
How to use this test
- Choose ANSI, ISO or JIS.
- Compare the physical key shapes and additional positions.
- Check your operating-system input language separately.
- Use Keyboard Test to inspect the events actually delivered.
What this test checks
- ANSI, ISO and JIS physical references
- Enter and left Shift shape differences
- Additional JIS keys
- Physical layout versus typed language
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
This reference does not detect the printed legends or active operating-system input source.
Common problems and troubleshooting
Compare the physical board before changing the operating-system input source. If the printed legends and typed characters differ, open Key Code Tester and verify layout settings rather than treating the reference image as automatic detection.
- Repeat the same observation. Focus the test surface and repeat “ANSI, ISO and JIS physical references” three times under the same conditions.
- Change one condition. Compare “Enter and left Shift shape differences” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
The reference uses static semantic controls and works without a device API. Exact manufacturer layouts can add or move keys, so the diagrams represent common standards rather than every regional or compact model.

Frequently asked questions
Is this Keyboard Layout Reference free?
Yes. The test works without an account, download or payment.
Is my test data uploaded?
Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Does this result prove my hardware is faulty?
No. It shows what the browser can observe. Repeat the test, compare another browser or device, and seek qualified support when the result matters.
