Yeah, keyboard binding consistency is what I really want. Ideally, you could choose between Vim, Emacs, <whatever else> keybindings for the program you're using.

I think what's also needed is a standard way of navigating what I guess I'll call the "focus tree". For example, if I'm running Vim inside of a terminal multiplexer (eg: Zellij) inside of a terminal emulator inside of a tiling window manager (eg: xmonad)...

It would be GREAT if I could use Vi keybindings to navigate windows in whatever "focus layer" I'm at... and then have a "standard" keybinding to navigate up and down that tree (eg: "Ctrl + >" and "Ctrl + <").

Right now, everyone seems to solve the "focus tree" problem by trying to choose a control key combination that won't collide with any other process that might be listening for key chords at the same time.
