No matter you do, inactivity means forgetting. Why do you need the api memorised if you don't use them?

I mean, using the editor itself means maybe 10-15 keys/commands.

Mastering Emacs is a good overview, btw.

Yeah, the book is definitely worth the asking price.

It's worth noting that you'd have to pay for the book only once. Every new edition you'd get for free. Mickey keeps the book updated and relevant for every new release of Emacs.
