 - **🔭 Satellite passes:** Ask by voice when any loaded satellite next rises over you: rise, peak and set times, and whether you can see it.
 - **🔎 Analyst answers:** Count, filter and rank satellites, datacenters and dams by voice, alongside flights, ships, fires and quakes; answers say when a feed is stale or on a fallback.
 - **🧭 Tilt and North Up:** Switch between straight-down and a 35° oblique, or put north at the top, while a tracked target stays centered.
-- **🔍 Keyless search:** Type coordinates or a bundled city or landmark to fly there with no network request; other names use Google when configured, then Photon and Nominatim.
+- **🔍 Keyless search:** Type decimal coordinates, a two-dimensional WGS84 `geo:` URI (for example, `geo:39.7392,-104.9903`), or a bundled city or landmark to fly there with no geocoder request; other names use Google when configured, then Photon and Nominatim.
 - **📦 Shareable scenes:** Import, preview and share Director scenes as files or bundles, with camera anchors, authored moves and data packs.
 - **🌊 Nepal flood scene:** Replay the Bhote Koshi flood: flood path, witness sources and before-and-after imagery (bundled data is non-commercial; see [DATA_SOURCES.md](DATA_SOURCES.md)).
