Tool description

JavaScript Key Code Identifier is a handy tool that shows you exactly which key codes and properties are triggered when you press keys on your keyboard. Perfect for identifying JavaScript onkeydown keycode values, this tool instantly displays key event properties without requiring you to write any code. Whether you need to find the Enter key code in JavaScript or any other keyboard event value, simply press a key and see all its properties immediately.

Use cases

  • Web developers building keyboard shortcuts or hotkeys for their applications using JavaScript onkeydown keycode detection
  • Game developers implementing keyboard controls and need to identify specific key codes

  • Determining the correct key codes to use in your JavaScript event listeners and handlers
  • Debugging keyboard event issues across different browsers and operating systems

  1. Click anywhere in the tool and press any key on your keyboard
  2. Instantly see the key properties displayed in the output area

  4. Copy any values you need with the copy button

Available properties

  • Key: The value of the key pressed (e.g., "a", "Enter", "ArrowUp") - useful for modern JavaScript onkeydown keycode detection

  • Ctrl key: Whether the Ctrl key was held down during the keypress
  • Shift key: Whether the Shift key was held down during the keypress
  • keyCode: The deprecated numeric key code (included for legacy compatibility, e.g., Enter key code JavaScript value is 13)
