Command entry:Keyboard Alt+Z (3ds Max mode) turns on Zoom ; [ zooms in; ] zooms out
Command entry:Keyboard Ctrl+Alt+middle mouse button (drag) (3ds Max mode)
Command entry:Keyboard Alt+right mouse button (drag) (Maya mode)
Command entry:Roll your mouse scroll wheel (either mode).
Note How you navigate viewports depends on which interaction mode, 3ds Max or Maya, is active. To zoom in in 3ds Max mode, drag the mouse upward; to zoom in in Maya mode, drag the mouse down and to the right ("southeast"). See Mouse Panel.

When Zoom is active, you can adjust the view magnification by dragging in a Perspective or orthographic viewport. By default, zooming occurs from the center of the viewport.

TipIf you use a wheel mouse, you can turn the wheel to zoom the active viewport in and out without first activating Zoom. The zoom center is the center of the viewport.

Zooming takes place incrementally, based on the distance between the viewpoint and its “virtual target,” an inaccessible hidden target used for calculation purposes only. Use the Ctrl and Alt keys, respectively, to increase or decrease the increments. You can move the virtual target by holding down the Shift key during a zoom operation. Otherwise you will zoom increasingly closer to the target, which does not move.
