React component to listen to keydown and keyup keyboard events, defining and dispatching keyboard shortcuts. Uses a fork of hotkeys.js for keydown detection of special characters. You give it a keymap of shortcuts & it bind it to the mousetrap singleton. The, it'll unbind it when the component unmounts.

react-hotkeys-hook - React hook for using keyboard shortcuts in components. Make sure that you have at least version 16.8 of react and react-dom installed, or otherwise hooks won't work for you.
