Most functions on the map are accessed by the Right Click menu.
Right click on the map to access generic functions, and right click on a track, route or waypoint to access functions relating to that particular item.
Some functions use the actual location you clicked on the map, for example, Add Waypoint puts a waypoint at the location that you right clicked.
Map type selector
You can choose between Map (Google Map), Satellite (Google Satellite view), OSM (OpenStreetMaps), or OS (Ordnance Survey).
Note that selecting a map rendering other than Google Map does not affect routing - it will always route using Google no matter how you display the map.
