+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.
