Keyboard Test

물리 키보드의 입력, modifier, numpad 인식을 브라우저에서 점검합니다.

Physical keyboard test

Focus the test surface and press keys on your physical keyboard. Active keys light up immediately and tested keys remain marked for the current session.

Press keys here to start testing. This surface keeps focus so you can test arrows, space, tab, modifiers, and numpad keys more reliably.

Browser limitations

  • Some operating system and browser shortcuts never reach the page.
  • The Fn key is not reliably exposed as a standard browser keyboard event.
  • Non-standard hardware layouts may appear in the fallback detected-key list instead of the visual layout.

이 도구로 무엇을 할 수 있나요?

A keyboard test tool checks whether physical keyboard keys are detected correctly in the browser. This version highlights pressed keys, keeps track of tested keys, and shows event details for modifiers and numpad input.

  • Live full keyboard visualization
  • Left and right modifier key detection
  • Numpad and arrow-key checks
  • Session-based tested-key progress with local processing

이런 경우에 유용해요

  • Check whether a laptop or external keyboard key is physically responsive
  • Confirm left and right Shift, Ctrl, Alt, and Meta keys separately
  • Verify numpad keys and arrow keys after hardware changes or cleaning
  • Diagnose stuck-key or missing-key behavior in the browser
  • 원고/문서 편집
  • SNS/메시지 작성
  • 텍스트 정리
  • 복사/붙여넣기 작업

  2. 2Press the physical keys you want to verify on your keyboard.
  3. 3Watch the matching keys light up on the visual layout and remain marked as tested.

자주 묻는 질문(FAQ)

Does this keyboard test work with mobile keyboards?
No. The first release is designed for physical desktop and laptop keyboards, not mobile virtual keyboards.
Can it distinguish left and right modifier keys?
Yes. The tool surfaces separate codes for keys such as ShiftLeft and ShiftRight when the browser reports them.
Does it test numpad keys separately from the number row?
Yes. The visual layout and event details treat numpad keys as a separate cluster when the browser exposes numpad codes.
Why do some keys not appear in the browser?
Some keys and shortcuts are reserved by the operating system or browser. Hardware-layer keys such as Fn are also not reliably exposed as standard browser keyboard events.
Do you store my keyboard input?
No. The tool runs entirely in your browser and does not send your key events to a server.
