Standard Standalone? yes
What are you trying to achieve?: use ‘left shift’ and ‘right shift’ for a true/false questions task. However PsychoPy stores any shift press as ‘left shift’ press.
What did you try to make it work? checked with another program if it’s my keyboard or OS problem but in this program (SharpKeys) both shifts are recognized correctly.
In the image a piece of output. As you can see the keypress in all cases shows as ‘left shift’ even though I pressed the right shift in more than half of the cases.
