n / N step through the files of a multi-file diff one at a time, which
is tedious when the diff spans many files. Add `f`, which pops up a menu
listing every file in the diff — in the order they appear, as
repo-relative paths — so you can jump straight to one.
The menu title and the keybinding description are hard-coded English for
now; this is a prototype.
