Recently the zoom functionally just stopped working for labview on my computer and I cant get it to come back. It used to be ctrl and mouse wheel to zoom, now that behavior scrolls through the cases on case structures. I have also tried looking for the shortcut in the tools>options>menu shortcuts to change it back, or to anything but unless I missed the option it's not there either. Ctrl + and Ctrl - dont do anything to zoom either. Has the hotkey changed to something new, can I change it back to just be a mouse wheel?
Solved! Go to Solution.

There is an ini-key in labview.ini to change it between Ctrl-mouse and Ctrl-shift-mouse, or disable it.
Editor.Zoom.BlockDiagram.MinFactor=2
Editor.Zoom.BlockDiagram.MaxFactor=0,5
Editor.Zoom.MouseWheelGestureRequireShift=True

These lines weren't originally in my configuration file and after pasting them into the file I was still unable to zoom. Is there something else that I need to do to enact the changes?

You shouldn't need it, but try adding this line also:
Editor.Zoom.BlockDiagram.Enabled=True
(and restart LV)

I added the lines in the .ini in the labview 2023 folder shown in the screenshot but I'm still not able to zoom with ctrl mousewheel, ctrl shift mousewheel, or ctrl +. Any other ideas?
--- edit---
I also closed and reopened labview

Oh, 2023? I think it was introduced in 24!
