Qt5 docs about this: http://doc.qt.io/qt-5/focus.html Yes, you are right, [Shift-Tab] should cycle through the widgets in the reverse order that [Tab] does. But I am not sure how much influence we have on that from the UI side; this should be done automatically by Qt. If the forward tab order works, the reverse order should work as well. We'll need to investigate this more deeply once we have some breathing space (which now we clearly don't).
