Questions about Selections

Hi all,

I have some unsolved questions about selections, I have panel, ASB, CSB, layoutSelectionBoss and so on:

1. How is my selection called? What steps I need to do for that?
2. How to get data from selection? There shlould be defined abstract methods in ASB, and its real implementation in CSB or eg. LayoutSelectionBoss?

Thank you in advice
