Just a caveat: the space has the current language written on it, which might suggest long-pressing it will get you something related to that (that's what it does on other platforms). Maybe we can differentiate between a horizontal drag and a long press.
Wonder if double-tap-drag could give us text selection on top of that (could be tricky to differentiate between all the different modes - but maybe it's doable).
