I'm running my AC12 with my AC11 Work Environments imported, so it might be related:
If I select Standard Profile 12 as my work environment, nudge works. If I switch to my AC11 profiles, in which I use the up/down arrows for moving upstairs/downstairs, and the left/right arrows for toggling between current tool/Selection arrow and Going into current tool Properties, then Nudge doesn't work.
So: how do I control the Nudge shortcut? I can't find them in Shortcut schemes in Options>Work Environment>Keyboard Shortcuts.
