^^this I also had the same issue, oddly enough it got worse as i got more accustomed to the program. I think mainly because I was visually counting the boxes from the right to left. maybe instead of boxes use a numbering or finger image? But yeah definitely some differentiation between the 'f' key and the 'space' key
