I'm mostly ok with variety. Helps keep me thinking about what I'm doing. Well, as long as the shortcuts they use actually make sense. As I said in a sibling, why is C-d bookmark?! At least C-f for "forward" makes sense.
It is surprising how "discoverable" many of the keyboard choices are/were in older editors. In emacs? C-c C-(first letter of what you want to do) probably works if you are in a minor mode. If not, try C-h b to see the bindings.
