Hi @shanr
We are currently updating the fundamentals of animation course. One thing I would 100% advise against is not changing the “Only insert needed” setting. Chris mentions to change this – but don’t. Never do this. It is bad advice haha!!
The others have already mentioned where the Auto keying is, but I don’t think you will need a hot key for this. You probably won’t be switching on/off all that often. (mine is on 98% percent of the time).
Let me know if you get stuck on any animation related things.
