Keyboard Commands For Zoom For Mac

Hi,
I'm so sorry for all the posts recently. When I tried to do a search for my question, I couldn't find what I needed. Maybe I'm just not good with tech.
I'm just wondering if someone could tell me how to turn my video on and off using V? It's probably really easy but I've never used Zoom on a mac before.
If you could let me know, that would b brilliant.
Thanks so much.
