Zoom adjusts view magnification in the active viewport where you drag. By default, this button zooms in and out of the center of the viewport.

Tip: If you use the Microsoft IntelliMouse or a compatible pointing device, you can roll the wheel to zoom in and out in the active viewport. The zoom center is the current cursor position.
