Zoom + to zoom-in with double scale factor. Zoom - to zoom-out with half scale factor.

You can also zoom with the scroll mouse. Zoom will center to the location of the mouse.

NOTE: There is a problem with snapping when not using a scale factor of a multiple of 2. Recommend only using the scroll mouse for read only actions and runtime interactions. Editing should be done when restore the zoom using the origin and using the zoom +/- to scale with a factor multiple of 2.
