APM session.ui.mode values

I looked around and couldn't immediately find the answer. It would be good to get this fixed in the documentation. Could you open a support ticket and simply ask this question and request that the documentation be fixed?

This session.ui.mode isn't so interesting from an outside perspective because it's used internally by APM to determine what resources/pages to deliver to connecting clients. Most of the time you'll want to use the other variables that have the specific platform or raw user-agent.
