Next change (F8) skips forwards to the next point of difference between the files or in outline mode to the next file with status "different"

Rescan selected file recompares the selected file. If a file is unreadable for some reason (e.g. access denied because opened with DENY_READ by another process) then this allows you to try again for that file. This can be useful for tidying up loose ends, especially when doing large comparisons involving thousands of files.
