This course looks amazing!
I watched ahead some, and just wanted to warn beginners: no screen keys are used in any of the videos (that I've found).
I've never done any rigging, so this is all new to me.
Recommendation: Re-recording seems overkill, but it would be nice if you might manually annotate some key (pun intended :D) rigging hotkeys that will be new to us beginners.
Thank you for this awesome course!
