/*
** Diff keyboard navigation shortcuts:
**
** ### NOTE: The keyboard shortcuts are listed in the /vdiff help screen. ###
**
** Ideas and TODOs:
**
**  o The `timeline-keyboard-navigation' branch removes the unload handler from
**    pages containing timeline snippets, so it's no longer necessary to reset
**    the diff toggles on back/forward navigation in case the mentioned branch
**    is merged with `diff-keyboard-navigation'.
**  o The `diff-toggle' class was renamed to `toggle-diff' in my private Fossil
**    patches to simplify completeness tests with my IE-compatible builds.
