This is not only for local pages, but seems to be a general new feature where G detects and lists items for pages in SERP.
I have a site having keyboard shortcuts and G does NOT itemize it. Try for example 'excel shortcuts', my page (shortcutworld) is in the top 5 and does not list the items. However, other pages further down do.
I'd love for G to detect mine as items as well, but cannot figure out why some pages are itemized and mine are not. I checked the sources and they all list their items in tables as I do. Maybe there is some meta-information I am missing?
Anybody having any inputs?
