I'm just starting using Direct To Web in earnest, and something I'm finding very difficult is knowing what keys to use to do the things I want. Sometimes they're mentioned in the JavaDoc, but sometimes they aren't. I thought I'd start this page and add to it whenever I spent a while trying to find something.
Query All Page
Array of strings
Controls which entities the Query All page will let you query. If this key is absent, it lists all entities.
