Keyboard control of selected objects in the UI strikes me as tricky, though I guess it will be easy as soon as somebody rolls a good plug-in for it. But I’m guessing that we may have to “make do” with a much-upgraded Navigator that is coming soon. Who knows though, these guys are full of surprises.
