hotkeys

Just found blog post on hotkeys and tried it out.  Can't seem to get hotkeys to work.  Hotkeys 1-5 are supposed to allow you to rate yourself, but when I press any of them, I get no response.  Not sure what I'm missing here to get them to work.  Any suggestion would be appreciated.

Hi Chris7650, 

I apologize for any confusion caused; here are the hotkeys you can use: 

P = Play tutor audio
R = Record yourself
Enter = Reveals phrase
1 = rate as Hard
2 = rate as Good
3 = rate as Easy

Kind Regards!
