What this tool does

The keyboard test displays pressed keys and the key codes reported by the browser. The check runs in the page and requires no additional software.

How to use the tool

  1. Focus the test area and press individual keys.
  2. Compare the displayed name, code, and modifier information with the key you pressed.
  3. Reset the list before starting another test run.

Useful applications

  • Checking an external keyboard after connecting it.
  • Investigating key mappings or modifier keys in a browser environment.
  • Inspecting keyboard events while developing a keyboard-driven interface.

Notes and limitations

  • Browser or operating-system shortcuts can capture some keys before the page receives them.
  • The page reads keyboard events in the browser; it cannot diagnose the physical cause of a hardware fault.

Frequently asked questions

Why is a key not displayed?

A browser or operating system may capture the shortcut first. The focus may also be outside the test area.
