Emacs has something like that as well with the right plugins. Ctrl+h f then fuzzy type what you want to do. Or, like usual, alt+x then start typing to just execute that command instead of reading about it. You just need the plugin Helm, or Ivy. I use Doom Emacs, and this functionality is built in. I use it all the time. Same story with config variables, except it's ctrl+h v instead of f.
