How to replace a region in emacs with yank buffer contents?

Question

When I use VIM or most modeless editors (Eclipse, NetBeans etc.) I frequently do the following. If I have similar text blocks and I need to change them all, I will change on

Answer 1

For anyone landing on this who doesn't want to change the global setting like me, I use this function and key binding:

(defun replace-yank(beg end)
  (interactive "r")
  (kill-region beg end)
  (yank 3))

(global-set-key (kbd "C-S-y") 'replace-yank)

I intentionally add the selected text to the kill ring incase I want it later, and yank what was previously first in the ring.
