No, there is no dedicated BBM BlackBerry button or a
physical trackpad, but the whole
keyboard can act as a
trackpad — you can scroll up and down or swipe left or right by just moving your fingers
on the
physical keyboard, which might seem initially unusual but is rather cool, once you get the hang of it.
Of course, it's worth noting that not all Android apps will run
on it as well as they do
on mobile devices when the feature is launched; developers might need to optimize their software to work better with
trackpads and
physical keyboards.
