I'm just starting to learn QGIS. I'm starting with the basic simple things. Coming from an ArcGIS background, I am used to the mouse wheel action zooming in and out the default ArcGIS way. QGIS default is the opposite. The only option I seem to find about changing mouse action options is to enable or disable the mouse wheel action, but nothing about the altering the action. Can I do this?
No, it's not possible to change the direction.
In Options, you can change the zoom speed and behavior (zoom to mouse cursor, zoom, etc.) but not the general direction.
