> is it possible to change the exit page when you press CTRL Q or CTRL B?
Yes, you should be able to set the finishpage based on the respective response:
<block myblock>/ ontrialend = [
if (block.myblock.response =="CTRL+'Q'" || block.myblock.response == "CTRL+'B'")
defaults.finishpage = "http://sad.trom.bone/"
/ trials = [1-4 = mytrial]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
/ items = ("<%trial.mytrial.trialcount+1%>")
/ columns = (blocknum blockcode trialnum trialcode latency response defaults.finishpage)
/ separatefiles = true
