Hmm…not efficiently, slate knows the native widget with focus, but we don’t have a way to know which UWidget has the focus. You can ask the UWidget if it contains the focus, but you’d have to loop over them all to find the one with current focus.
Slate already attempts to move focus in a simi-smart way when you press tab, though may not work on modal screens since the modal root is eating all the keys. May need to add some special logic there.
