DOn't feel bad for asking questions- it's how I learned.

You can also determine which item gets focus first by arranging your tab order. This is what allows you to set in which order objects get focus when the user hits the tab key- it's always a good idea to set this up, otherwise you could have users randomly jumping between objects with no real rhyme or reason. Whichever items is first in the list is the one that will start with focus.
