How can I use a bluetooth remote to pause a video on Keynote?

I used to use a bluetooh remote to pause videos on Keynote during my presentations. However, since the Keynote update to 6.2 I am no longer able to do it and it was a very helpful tool for me. I use the Satechi bluetooth remote GBR-100 for that. I use the MacBook Air which does not have the infra red remote capability. Is there any possible set up that I can try?

Thank you!
