This is meant for special purpose cases where we need to talk directly to some GWT code. Its a JSO-based API at present, and can pass Element/WebElement back and forth as well. In this case it deals with the trigger icon, which can't be manipulated otherwise, since there isn't some good cross-appearance way to talk about the trigger icon. Since it is a thing to be clicked, all I hooked up was clicking that icon.

This is the same mechanism that the ByWidget and ByNearestWidget are implemented with, along with other parts of the GwtWidget type. This is somewhat subject to change, though the stuff that uses it will remain more or less the same. 

Not totally sure this actually works.
