useKeyPress

This hook lets you listen for specific key codes and tells you whether they are currently pressed or not.

import { useKeyPress } from 'reactflow';
 
export default function () {
  const spacePressed = useKeyPress('Space');
  const cmdAndSPressed = useKeyPress(['Meta+s', 'Strg+s']);
 
  return (
    <div>
      {spacePressed && <p>Space pressed!</p>}
      {cmdAndSPressed && <p>Cmd + S pressed!</p>}
    </div>
  );
}

Notes

This hook does not rely on a ReactFlowInstance so you are free to use it anywhere in your app!
