Using a Bluetooth Keyboard with Ipad for Lingq

I’ve been getting pain in my hands from using my Ipad for Lingq and thought that it might be better with a bluetooth keyboard instead.

Everything works fine with changing the status of words and scrolling down the lesson in classic mode but I can’t scroll through Lingqs using the arrow keys and have to touch the ipad screen to move to the next unknown word or Lingq.

Does anyone know a way to get around this problem?
