I’ve just recently started using the audio review feature and unlike the other kinds of review, the numpad doesn’t work. Normally I can select an option using either the numbers along the top of the keyboard or the numpad, but in audio reviews pressing a numpad key does nothing.
The keys along the top are so much more awkward to use.
Same problem here! That’s very annoying, because the NumPad is very conveniently positioned - you can access all the numbers and Enter with just one hand. Does anyone know why it doesn’t work?
Btw, to clarify, it only doesn’t work for the questions where you have to select one of the multiple audio options to match a written word. It works when you have to select one of the multiple written words/phrases to match the single audio. (At least in my experience.)
To be quite honest, this seems like the “listen to audio” buttons are slightly different from the others (software-wise) and that someone simply forgot to link the Numpad to them. At least I hope that’s the case, 'cause that would be easy to fix! 
Is this ever going to be fixed?
Anything? Come on, Memrise team, this can’t be a complicated issue, right? Or, if it is, at least tell us so…
