How to move the Agent with a Mac laptop?

We got stuck on the second lesson by don’t know how to move the Agent, please help…

I found out how… so happy!!!

Another question comes up, why I can’t watch the same video for the second time?

Where to find the video in the beginning of the class? Once student watched, it won’t show again in the same computer.

Hi Wendy,
If a level has a video, you can usually re-watch it by clicking the thumbnail located under the Run button. In this case, you’d need to back up to Level 1 first. Hope this helps!
