Selecting an item programmatically

[slickorange]

How do I scroll to an item programmatically?

Also, how do I scroll "past" the beginning or end so that the first or last items of the list can also be in the center and be "selected"

I am using this for a selectable list of items.
Items can be selected either by:

• tapping on them (triggering a scroll to put the selected item in the center)
• scrolling until the item is in the center
• Programmatically by updating the selected index from another function

Would this be possible?
