How to stop / kill a half-completed experiment

I’m certain this has come up before but a search proved fruitless.

I was wondering if there is a way to stop / kill an experiment mid-run. I have an experiment with a lot of stimuli and I don’t want to have to run through the whole thing every time I go to check my coding works.

Thanks.

Your experiment will stop running if you press the escape key. If this is not working, you might have your experiment set not to end on a response.
