Volatile Highlights

The package volatile highlights temporarily highlights changes to the buffer associated with certain commands that add blocks of text at once. An example is that if you paste (yank) a block of text, it will be highlighted until you press the next key. This is just a small tweak, but gives a nice bit of visual feedback.

You can install it in the normal way:

;; volatile highlights - temporarily highlight changes from pasting etc
(use-package volatile-highlights
  (volatile-highlights-mode t))
