Whats wrong with Ctrl-Q, type "String", hit return, Select ::String. You don't even have to open the file! Looking at the source is almost always the easiest way to find something out (one of the reasons I like Upp so much actually).
And as far as I can tell, every class that you could conceivably need to be Moveable is, with the obvious exception of Ctrl derived classes.
And just for completeness: Only Vector requires Moveable, Array does not.
