Yes, it is mentioned in the article and it even has that link: > However, the kitty keyboard protocol has been widely adopted by both modern terminal emulators and terminal applications. Terminals which support the kitty keyboard protocol (to some degree) include Wezterm, Alacritty, kitty, foot, Ghostty, and iTerm2. > Applications which support the kitty keyboard protocol (to some degree) include Vim, Neovim, Helix, kakoune, and nushell. This means that when using one of these applications in one of these terminals, all of the key encoding problems discussed above (as well as some others which were not discussed…) are solved.
