function useHeldKeyCodes(): Record<string, string>;

Defined in: useHeldKeyCodes.ts:30

React hook that returns a map of currently held key names to their physical event.code values.

This is useful for debugging which physical key was pressed (e.g. distinguishing left vs right Shift via "ShiftLeft" / "ShiftRight").

Record<string, string>

Record mapping normalized key names to their event.code values

function KeyDebugDisplay() {
  const heldKeys = useHeldKeys()
  const heldCodes = useHeldKeyCodes()

  return (
    <div>
      {heldKeys.map((key) => (
        <kbd key={key}>
          {key} <small>{heldCodes[key]}</small>
        </kbd>
      ))}
    </div>
  )
