The probe can be adjusted to fit in the current region or data domain (while retaining the current orientation) using the "Fit to Region", "Fit to Domain", "Crop to Region" and "Crop to Domain" buttons. "Fit to Region" will expand or contract and translate the probe from its current location to be maximal within the Region. If it is outside the region, it is first translated to the region center and then maximized to fit. "Crop to Region" reduces the probe to fit in the current Region. Similarly the probe can be fit or cropped to the full data domain.
