toolbar manipulation w/ lisp

I can show, hide and place toolbars using lisp.

How do I close or reset a toolbar placement with lisp?

Hiding "hides", but the toolbar remembers its last location, which gets in the way of redefing placement.

(command "-toolbar" "all" "hide")

(command "-toolbar" "standard" "show")

(command "-toolbar" "standard" "top" "0,0")

Or, what is the lisp equivalent of right clicking on the toolbar area and "unchecking" one or more of the selections"?

Hello,

here is the one with workspace .

(command "_.wscurrent" "[color="Red"]Your Work Space Name[/color]" )
