ShowMap

Syntax:

ShowMap MapMarkerID, enableFastTravel (optional) 

Example:

ShowMap SecretDungeonMapMarker ; show SecretDungeon on world map, but don't enable fast travel
ShowMap NotSoSecretVillageMapMarker, 1 ; show NotSoSecretVillage on world map
                                       ; and immediately enable fast travel to it 

Adds the specified map marker to the player's world map. The player will still not be able to fast-travel to this location until she or he actually travels there once unless the optional enableFastTravel parameter is set to 1.
