iPhone: Question about keyboard / drawing

If I want to implement my own keyboard, I'd like it to behave similarly to
the built-in iPhone keyboard.  Specifically, when a key receives a 'touch'
it pops out above the key, so the user can see it.  As I understand, the
UIKeyboard class is derived from UIView.  When you touch one of the keys on
the top row, it pops out outside the bounds of the UIView - how would I go
about doing this 'correctly'?
Cheers,

Stuart
