I often want to jump to the last change I made in a buffer, but I've
never wanted this across buffers.  The method I use for this, burned
into my fingertips, is "C-_ C-SPC C-_", which is undo, set mark, undo.
The set-mark causes the second undo to redo and could be replaced by a
cursor movement instead, if one didn't want to mess up the mark
location.

So, although, once again, this doesn't work across buffers, using the
undo list might be helpful for coding such a feature.
