Hello Sílvia,
Yes, you can use Key elements as usual. Just remember that the script runs top-down and pauses on every wait command. Here’s an example:
newTrial(
newText("Press Space when you see another boat in the video").print()
,
newButton("Watch video").print().wait().remove()
,
newVideo("video", "https://upload.wikimedia.org/wikipedia/commons/4/4f/CanoeTacking.webm")
.size("auto","60vh")
.print()
.play()
,
newTimer("tooearly", 2500).start(),
newTimer("toolate", 3500).start()
,
newKey(" ").wait()
,
getVideo("video").pause()
,
getTimer("tooearly").test.ended()
.and( getTimer("toolate").test.running() )
.success( newText("Good job!").print() )
.failure( newText("Too early, or too late!").print() )
,
newButton("Next").print().wait()
)
