Stepping back with View-Unfocus is not possible?

From Help Documentation citation:
“OmniOutliner retains a history of the rows you’ve focused on, and you can step back through that history by choosing View ▸ Unfocus (Option-Shift-Command-F).”
I could not reproduce this “stepping back”.Is there a Youtube or other video showing it

By the way: it is very difficult to scroll or paginate (with either mouse or arrows) in the help documentation
