So I simply run diff and redirect its output to a .diff file, which is easily small enought to visit and navigate in Diff mode. What I'd like at that point is a command to highlight the changed text within the current hunk, just like "*" does in Ediff: ,----[ C-h k * ] | * runs the command ediff-make-or-kill-fine-diffs | which is an interactive compiled Lisp function in `ediff-util'. | (ediff-make-or-kill-fine-diffs ARG) | | Compute fine diffs. With negative prefix arg, kill fine diffs. | In both cases, operates on the current difference region. `---- Is there any way to take advantage of the Ediff machinery inside Diff mode? I don't have an answer for you, unfortunately. I do have some code that improves the highlighting of regular `diff' output slightly: http://www.emacswiki.org/cgi-bin/wiki/diff-mode-.el, but it doesn't do what you're asking.
