Viewing a waypoint's information

To view the name and details of a waypoint, tap or click on it on the map. A tooltip will appear with all the usual information: name, latitude/longitude, altitude.
On the mobile app, you'll also see the distance from the starting point.

Only on Android, holding a red waypoint will allow you to copy the waypoint's coordinates.

You can make this tooltip disappear by tapping the waypoint again or anywhere else on the map.
