i3wm/sway - lets me navigate windows with vim-like keyboard motions Neovim - best power editor, hands down. But it takes a bit of tweaking. Tmux - lets me have multiple terminals up in one window. Make/CMake/whatever the project uses. I also write scripts for anything that causes friction which can be automated. Vimium/VimiumFF in the browser - lets me navigate most webpages with just the keyboard.
