[[https://endlessparentheses.com/emacs-narrow-or-widen-dwim.html][Emacs narrow-or-widen-dwim]] Narrowing means focusing in on some portion of the buffer and widening means
focussing out on the whole buffer. This allows to concentrate temporarily on
for instance a particular function or paragraph by removing clutter. The "Do
What I Mean" [[https://endlessparentheses.com/emacs-narrow-or-widen-dwim.html][narrow-or-widen-dwim]] function allows to toggle between narrowed and
widened buffer states.
