Press space to start.
Scripts for @ContourLines I made it work somewhat better and I have also improved the key presses, now it works more like a normal keyboard, although it is more complicated. ISSUES Hold a non a-z key, then hold shift, then let go of the other key and finally let go of shift OR Hold shift, hold a non a-z key, then let go of shift and then the other key. If you press the key again it fixes it. (may have to hold shift) It seems to be a Scratch bug so I can't fix it.
