• Switching between different distributions: Chemacs

• Modes

  • Major Mode: Determines the behavior of shortcuts, highlighting, etc. It is often determined by the filetype. Can also be changed, e.g. M-x org-mode.
  • Minor Mode: Controls smaller features like linting and auto-complete. You can enable multiple of these at a time.

• Hook: A hook is a Lisp variable that contains a list of functions that are run on well defined occasions, like, when exiting Emacs or initializing a major mode. The add-hook command adds a function to a hook: (add-hook 'text-mode-hook 'auto-fill-mode)
