Ah, good, I'm glad I didn't go off on a tangent too much there.
I can see that some kind of "[] Nudge keys override normal UI behaviour" check box might be possible - or something similar with related functionality - but, looking at the list of outstanding issues the developers are already working on, I really can't see it being a priority.
When there's so much new stuff being developed and so many other issues to fix I'd say that the developers already have too much to do.
I've a feeling that such functionality would have to override the standard UI behaviour in so many places that it would be very difficult/laborious to code and test, for very little return.
I don't mean to belittle your request - it's perfectly valid - but the developers have to weigh up how much time and effort would be used implementing, testing and maintaining something against how much effort it saves. And, if you think about it, saving a couple of mouse clicks every now and again - on a total global use of Scribus overall level - versus making sizeable changes to the way the software works on a basic level doesn't really weigh up.
By all means raise a poll if you want to. All I'm saying is that I can't really see anyone doing anything about it any time soon.
But, I'm not a Scribus developer and I've been wrong before so what do I know?!
Anyway, that's probably enough prattling by me on the matter. If you decide to take this potential feature request further I'll wish you good luck on your journey.
P.S. To formally request a feature see the advice(?) I gave you on your other recent topic.
