Animation.rb with zoom active

[glro]

i recently discovered the animation plugin in examples folder
http://www.sketchup.com/intl/en/developer/docs/examples

when i zoom full screen before launching animation, i have a global view, but if i want, during the animation, to look closer at the model, i have stop it, zoom in, and resume the rotation

is there a way to keep the zoom commands active during the rotation?
