Yes, you can do that. Firstly enable keyboard commands in the ZoomView. You can do that in the ZoomView Builder, or you can add the following tag to the ZoomView animation:
Evnt="1"
Shift zooms in, crtl zooms out and the arrow keys pan.
The following code shows how to apply zoom to a widget. Since keyboard commands are enabled, the key commands will cause your image to zoom in and out.
NOTE: I have changed <> to [] so that all the code shows correctly here.
