I want arrow button nudges to move selected items by 8 pixels. But this never works. It doesn’t even work evenly forward and backward (3 down arrows and 3 up arrows back don’t move the select item the same distance).
How can I make Axure move the selected item(s) exactly and only 8px at a time?
I think your spacing is 8px already.
Make sure the bottom y coordinate of the upper box is a multiple of 8px.
Shift+Down works fine.
Thanks. This is what I was afraid of. The nudge requires some precondition to be true so that it will move 8px. Such a precondition may be possible. Who thought such a simple feature (move exactly X pixels) would be so difficult.
Hi @scoobydoo,
Justin from Axure here 
We’re working on adding a preference that will let users set the distance widgets should move when doing a Shift Nudge (shift + arrow key).
If all goes to plan, this feature should be available in the next Release Candidate for Axure RP 10 later this month.
Hi, happy September! 
Quick update that the feature discussed in this thread is now available for download in the Release Candidate.
You can find the option under File > Preferences
