Removing focus via apple script

I know that the following sets the focus to a specific folder. And I know how to set it to all folders/projects… But how to remove focus from a document window completely?

tell application "OmniFocus"
	tell default document
		set folderList to folders whose name is "xyz"
		tell the front document window
			set focus to folderList
		end tell
	end tell
end tell

Thanks

Hey sandrok! You can do this by setting the focus to an empty list:

tell the front document window
    set focus to {}
end tell

Hope that helps!

It worked! :-)
And it makes a lot of sense, now that have said it :-D

Thanks!
