On my 40D, after pressing one of the settings buttons on top of the camera (AF/Drive, ISO/EC, etc.) they timeout after six seconds. Am I missing a Cfn that could extend that time? I don't think I am, but wanted to ask in case. Given all the other flexibility, I'm curious why this isn't configurable. I just don't see a drawback to being able to extend that time to a timeout.
