Locations Editor
The Locations Editor is a modal window for maintaining your library of geographic places. Each location stores a name and its coordinates, so you can cast charts for a place without re-entering its latitude and longitude every time.
Open the editor from the main window's Edit menu by choosing Edit → Locations.
Locations are saved to the shared R7Data folder on your computer. This library is shared with the other Rhythm Seven applications installed alongside Compass, so places you add here are available to those applications as well.
Location grid columns
Locations appear in an editable grid with the following columns:
| Column | Description |
|---|---|
| Name | The location's descriptive name, for example "New York". |
| Latitude | Latitude in decimal degrees, from -90 to +90. Editing this value re-resolves the location's time zone. |
| Longitude | Longitude in decimal degrees, from -180 to +180. Editing this value re-resolves the location's time zone. |
| Height (feet) | The elevation of the location. |

Adding a location
To add a location:
- Click the Add button. A new, empty row is appended to the grid and selected, ready for you to fill in.
Editing a location
Every column is editable: Name, Latitude, Longitude, and Height. To change a location's details:
- Click the cell you want to change to enter edit mode.
- Type the new value.
- Press Enter to commit the change.

A single click on a cell enters edit mode. You do not need to double-click. Press Tab instead of Enter to commit the value and move to the next cell in the row.
Deleting locations
To remove locations from the library:
- Select the location or locations you want to remove in the grid.
- Click the Delete button.
- Confirm the deletion at the confirmation prompt. For the confirmation steps, see Confirm at the Confirmation Dialog.

Saving your changes
To save the location library:
- Click the Save button. Your named locations are sorted and written to disk.
Closing the editor
To close the editor:
- Click the Close button.
If you have unsaved changes, an unsaved-changes prompt appears before the window closes. From that prompt you can Save Changes at the Unsaved-Changes Prompt, Discard Changes at the Unsaved-Changes Prompt, or Cancel Closing at the Unsaved-Changes Prompt.
