Follow a path in Google Earth

[wyatt]

Is it possible to define a path in GE and then have the camera follow it? I'd like to be able to navigate a specific path, following the topography. I have a space navigator and thought I could use that to control my movement but I can't move smoothly enough through the landscape. (Of course it has nothing to do with user error. ) Is there a plugin or any tips to make my virtual trip smoother?
