Switch between zones from the zone selector — the menu that also holds all zone-wide actions.
To select a zone:
In the zone toolbar, click the zone selector — the button showing the current zone’s name and frequency count, e.g. Main Stage (24 freqs).
All zones in the site are listed alphabetically; the current one carries a Selected badge.
Click a zone name to switch.
Switching zones changes what the coordination list, plot, and Monitor tab show, and clears any selected group and pending candidate results. Coord remembers your zone selection per site on this machine.
