Zoom Excavation is a useful shortcut for quickly zooming in to the excavation(s) in your model, without having to use the Zoom Window option.
If your model consists of multiple excavations, Zoom Excavation will take into account the combined extent of all excavations.
Zoom Excavation is available in:
The Zoom sub-menu of the View menu,
The Zoom toolbar,
The F6 function key.
