This idea is currently in the LabVIEW NXG backlog. For LabVIEW 20xx, I'm moving the idea back to the 'New' status to be considered for a future LabVIEW 20xx release.
With a case structure I can place the mouse cursor over the structure and Ctrl + scroll wheel to cycle through the cases without it being active. If I try doing this on arrays it doesn't work.
For front panel arrays the numeric indicator must have focus for this to work. Doesn't work when the array data is selected. I understand that multidimensional arrays would be a problem, but for 1D arrays it would be nice if it cycled through the elements.
For array constant block diagram elements, no scroll action works regardless of what is active. Again it should allow the user to cycle through elements for 1D arrays simply by hovering over the item and Ctrl + scroll wheel.
