In a similar vein, I use a library called goto-chg.el that defines a 
goto-last-change function. I have this function bound to M-_, which nicely 
parallels C-_ for undo. It's especially handy on my laptop, where the 
touchpad sometimes sends me off to la-la-land when I accidentally brush 
against it with my palm.

Another implementation of this function by a different person is here
(I have not tried this one myself, but it looks pretty similar):
