Ah got it. Two sources I wish I knew about in the beginning are Xah Lee and Mastering Emacs. I linked keybinding specific pages, but both have a LOT of content and are super helpful. I’ve never read them start to finish, but just picked topics I was interested in learning about.
Yeah there must be some federation issue with that community. I have a Hexbear account so I replied with your comment and linked them to this thread
