I use ratpoison tiling wm with custom bindings, it's kind of tmux or screen for Xorg where you stack apps for example firefox, vim, ssh, tmux/screen, terms. Anyway, it's up to you how you search ctags, man, grep, web, etc

This setup is agile but still not as fast as lsp or copilot, but I prefer learning and remembering over speed, personal taste :-)
