Clearing the Screen 🔗
The *clear keyword allows you to clear the screen of everything on it. For example, you can have a program like this:
You'll now have 10 seconds to find the butterflies in this image. *image: https://1205271019.rsc.cdn77.org/images/research-guidedtrack/animals.png *wait: 10.seconds *clear *question: How many butterflies were there?
In this sample program, once the timer is up the instructions and the image is cleared from the screen and the user only sees the question, "How many butterflies were there?"
keyword operates much differently from
creating a page break
. With these latter options, the user has to click a button in
order to proceed to a new screen. With
, the screen clears automatically.
Note: Without the
keyword in place in this sample program, the user would not ever
see the instructions and image as the clear would occur
immediately. The user would only see the question. In most
cases, you'll want to use the
keyword after a
, unless you're using it to clear
