If ediff highlighting is confusing you....

then there is a simple configuration tweak to fix that. ediff highlights all the differences in a riot of colours and it takes some time to focus on the chunk that is highlighted or active.
A simple tweak that I found when browsing the emacs newsgroup. The settings makes only the current chunk highlighted thus making it simple to see the differences. Another minor change that can be set is the whitespace difference checking. I don't use it as I sometimes deal with data files and I need to see the spaces but otherwise it too is a simple fix when you're just interested in what's changed.



;; only hilight current diff:
(setq-default ediff-highlight-all-diffs 'nil)

;; turn off whitespace checking:
(setq ediff-diff-options "-w")
