  copy field 1 to stack "MyOtherStack"

The advantage to the "copy..to" option is that it preserves the user's
clipboard.

Could the stack's style property be set?  If so then "open" will honor the
style, while "toplevel" overrides the stack's style to open as toplevel
(same with the "palette", "modeless", and "modal" commands).

What is the mode of the stack when it's opened?

  open stack "foo"
  answer the mode of stack "foo"
