How do you programmatically manipulate system toolbars?

to some extent they can be handled like old FPDos style windows like:
ACTIVATE WINDOW "Form Controls"
DEACTIVATE WINDOW "Form Controls"

But how do you Dock them programmatically?

If you can get an object reference, you can just oTbr.Dock(0,x,y)
but, How to get the object reference?
