I was try to set key combination like shift+' with

(e.shiftKey && e.keyCode == 222)

but in parameter key it is only accecpt number and only one keycode. Is there any way to modify property key to make it can use key combination?

    tc.settings.keyBindings.push({
      action: "reset",
      key: Number(storage.resetKeyCode) || 82,
      value: 1.0,
      force: false,
      predefined: true
    }); // default: R

I'm newbie by the way trying to modify to learn a thing.
