Behaviors not showing?

Ive noticed today that I have yet to actually use a behavior. I think since torque script doesn't have much OOP ability like inheritance then I should be using behaviors right.

Well I have noticed that no matter what object in my game I click on there are no options in the behavior tabs drop down box.

Specifically what conditions must be met to use behavior code.

EDIT: ohh and good job whoever is redoing the TDN for TGB. I actualy just realized how much easier it would be to do a game coding objects instead of trying to shove everything into a few .cs files.
