Filtered Variables and kalman filter

I am using version 3.065

I use the filtered_var and smoother options in the estimation command. These variables should be stored in the oo_ structure in the results. Although, filtered_var, smoothed_var and smoothed-shocks are stored I cannot locate the filtered_shocks?

Does dynare calculate filtered shocks? If so where does it store them.

A technical question regarding Kalman filtering and Smoothing:

The Kalman filtered and kalman smoothed variables for the observables should always be equal to the actual observed values? IS that correct?

Thanks,
Abhishek.
