With the default keyboard/shortcut settings, Ctrl+MMB or scrolling the MMB wheel can be used to zoom in and zoom out.
The function was that up was zoom out down zoom in. That changed in NX11. Is there an option to change this?
What change did you see in NX 11 about this?
i think i got your issue now...but i too could not find any changes in NX11 in the behaviour of CTRL+MMB for zoom-in zoom-out
Customer defaults -> gateway -> view operations -> view operations -> mouse wheel scrolling direction. This option controls the direction of zoom for the mouse scroll wheel and also the ctrl + MMB. You will need to change this option and restart NX for it to take effect.
