List of Trait Expression queries

Hi,

Can you please someone provide me the list of syntax or expression use in Trait environment.

As I might already aware about the events, props and evars using trait expression.

For events we use c_events==scView

For evars we use c_evar5 contains "home"

For props we use c_prop5 contains "desktop"

But i would like to know the main/basic syntax for Pages, Operating Systems, Browser Type, Countries and more.... Could you please able to provide the list of variables or basic dimension associate with Trait expression list.....?

Thanks again!

Regards,

Vijay
