Zoom into an object in third person view

Im making a third person game. At a particular stage, I want to zoom into an item and then interact with it. So, if I go into a trigger box near the item and press a given key, the camera should focus on that item and then only should I be able to interact with it.
Also, If I have a static mesh of a laptop, and I want to use the individual keys of the mesh to accept input from user, what should I do?

double post…

I would switch the controls, and give the player controls to the laptop. Thus, i would make laptop the character, then zoom the view into the hi-res laptop view. While in this mode you would have to limit the view and prevent movement of the player. Maybe this can be just achieved with setting the movement option of the laptop to static.
