Hi Becky,
The “PressKey” part is the ID of the stimulus, not some kind of magic value that gets the RT of any stimulus. So you would either need a stimulus with PressKey as ID (which you can change in the JavaScript of said stimulus), or you would need to change PressKey to something else in the JavaScript I posted. Hopefully you’ll be able to figure it out from here!
Best regards,
Erwin
