im using the trackpad/magicmouse, and the suggested method wont zoom for me.
trackpad would be a two finger gesture, magicmouse would be a simple slide up or down.
both are configured for this functionality on my computers, and dont seem to zoom in or out 
thanks for your time and consideration![/quote:2gowcuh3]
These are the settings I use for Sentinel3 and the TrackPad works perfectly for two-finger zoom in/out as well as one finger tap & hold and another to pan the view around (when zoomed in).
