The default emacs keybindings strike me as particularly insane and not suitable for productivity or long term wrist health, but I use them because I don't want to go through every different mode as well as tmux, and my wm to figure out which bindings are going to clash.
I know that I should do it, but I'm lazy. If anybody has a really thought out set of bindings that are optimized for minimizing chords and sequence length as well as conflicts I would love to know about it.
What I'd really like is a scientific project to come up with a control scheme for the OS and emacs that maximizes keyboard efficiency.
