OpenStreetMaps interface with 8 map styles including Bing Maps Aerial and Terrai

[nanard31]

Hello every body

  I have used Plan-G for 2 years and discover that we can swap between 8 styles of map.
  [It is said "OpenStreetMaps interface with 8 map styles including Bing Maps Aerial and Terrain"]
 
  I can't find any button allowing these  8 choices in the menu or in the map.
