Zooming in on the XPression Viewport

Need to work on a small detail in an XPression scene, and want to zoom in really close? Top-notch operators would add another camera to the scene and move it very close on the Z-axis. Then forget about it and it might wind up on-air later. Now, it is possible to just zoom in the viewport while you work on it, as well as pan-and-scan the viewport to see exactly the detail you wanted, without having to use additional cameras or anything. Zoom through this video to get the details on how to do it.
