Navigating the Patcher window
The visible space in a patcher window is only a portal into a much larger space you can use when programming with Max. You can zoom in or out on a portion of the patcher you're working on, to view specific areas of a very large patcher.

Using Navigate Zoom
You can move the navigate zoom window around on your desktop, and click and drag in the lower right-hand corner of the Navigation window to change its size.
The navigate zoom window has a pale blue viewing frame that shows you a simplified version of what you're looking at in the patcher window inside the viewing frame.

Zooming In/Out on a Patcher
Note that the scale at which you zoom in our out is the same for both Patching and Presentation modes.
