So that you can communicate locations to your alliance, e.g. in battles, without having to type in the coordinates, you can send them to the chat with just 2 clicks. After clicking on the coordinates, the player jumps directly to the desired location.
Click with the right mouse button on the minimap where you want to enter the coordinates. Now the coordinates appear, for example "Send 87200 46259". Now click on it with the left mouse button and the coordinates will appear in the chat.
