The zone command shows atomic detail and residue labels near a specified single residue of interest. Density-map or other volume data displays can also be restricted to a zone near that residue, and different cutoff distances can be used for the atoms, residue labels, and volume displays:

The cutoff values remain in effect for automatic application with the zone command and/or zone mouse mode until they are explicitly changed or ChimeraX is exited.

The label option indicates whether to show zone residue labels (default true; false removes all residue labels). The ribbons option shows the beyond-zone residues of the same atomic model as a narrow ribbon (default true; false does not modify any existing cartoons).

The zone clear command clears the labels and returns to what was shown before zoning.

The zone setting command allows changing:

By default (save true), these changes are saved as preferences for zone labels only (not other labels). Enabling virtual reality automatically changes the zone-label color to yellow
and zone-label background color to black without saving these values as preferences.
