In Emacs, the way this is addressed is that commands that are likely to 
cause a big change in buffer position usually save the previous position 
automatically in the mark ring.  For instance, type M-> to jump to the 
end of the buffer, and it will display "Mark set".  The same thing 
happens when you perform a search.

You can then walk back through the mark ring by typing C-u C-space 
repeatedly until you get to the saved position you care about.
