I've done this:

    def keyPressEvent(self, event):
        if event.key() == Qt.Key_Backtab:
            event.ignore()
            newev = QKeyEvent(event.type(), Qt.Key_Tab, Qt.ShiftModifier)
            super(MessageEntry, self).keyPressEvent(newev)
        else:
            super(MessageEntry, self).keyPressEvent(event)

And it does do the back shift, but then the qsci widget loses focus.
Is there a way to avoid that?

Thanks.
