Hi all! I have a question on how to use keys to answer multiple choice questions. I noticed a few discussions on the topic, but the solutions did not work in my case.

I have a number of timed multiple-choice questions. Respondents should choose between “Same” or “Different” within 7 seconds. Each question is in a block with a timer and the question itself. It is also important the the time (and the response) are recorded, as it currently is the case with mouse clicks. Any help is appreciated!
