Yeah I'm a 20 year emacs user in the same boat. Kinda curious what the learning curve is like going from emacs keybindings to vim style modal editing. Bonus points if Dvorak typists can tell me what they do because I've been sadly typing in Dvorak for even longer than I've been using emacs.
As a Dvorak typist and Emacs user (repented from using Vim in the past), when I need to use a vi-like I just use the standard key bindings. Nothing good comes from rebinding keys in my opinion. But the way my brain works is by remembering that scroll down in Vim is Control + D and my fingers remember where Control and D are located on the keyboard.
