MarioRash said... Hello! 
Does anyone know how I could change the key that has to be pressed (instead of enter) to input an answer? 
I would love to change it because my little finger hurts after a hundred reviews and it sometimes hinders me from continuing. 
If someone could teach me how I should do it, or makes a little script for me, it would be lovely. 
Thank you in advance!
I believe there is a script that automatically enters once it recognises that you have put in the correct answer. I have never used it (sounded a bit too much like cheating to me), so I don't know if it is still supported or worked well.
