A little about the camera, without going into Lua scripting. To start with, in editing mode THERE IS NO FIRST PERSON CAMERA. in fact the camera doesn't even move, instead all the moving is done by rotating, tilting, and zooming the space. its a bit like that Futurama scene "Actually the ship doesn't go anywhere, we instead move the universe around it."
However, if you want to look at part of your model from any sort of first person perspective, there is a way. If you select a point within your model and zoom all the way in (mouse scroll wheel) until it stops getting closer, the camera will be at what i believe is its true location. Meaning now the camera's motion will not be orbiting around the focus point but right at that spot. it will be as if you were there, turning your head to look around.
