The arrow keys work fine in X and Y, both alone and with the Ctrl and Shift modifiers.
For nudging in Z, in Windows Rhino one uses the PageUp (+Z) and PageDown (-Z) keys. Those work fine without modifiers, but since recently Shift and Ctrl plus either PageUp or PageDown zoom the view instead of nudging.
So something got broken, this used to work correctly (and still does in V7).
Thanks for the bug report, @Helvetosaur. I just tested on Rhino 8.14.24332.15001 (2024-11-27) and I can replicate the problem while nudging without Alt and trying to use Shift or Ctrl with PageUp or PageDown. Can you share Rhino’s SystemInfo, so we can attempt to isolate the problem to a specific version?
