Paste a lesson to begin.

Aster reads the captions, looks at the frames, and speaks only where the screen carries something the narration leaves out.

Ask about the screen

Press V and say “what’s on screen”, “read the code”, or “ask” and your own question. I pause the lesson, look at the current frame, answer out loud, then resume.
