In LSI, I want to filter something by a board or category ID, but it's asking for a numeric value. How do I get the numeric values for board and categories?

Back in the day the IDs were surfaced directly in the URL. Users didn't really understand what they were and it provided no value from an SEO perspective. Thus they were phased-out of the URL when SEO-friendly URLs were brought in.
IMO the IDs should be surfaced in the Community Structure tab somehow.
