Click on the yellow ‘i” icon at the upper left part of the screen to reach the information panel. No actions can be taken using this panel. Here you obtain different sorts of information by clicking on any country on the map.

There are four small icons in the center of the upper part of the screen. Each of these icons provides access to different information about any country you click on : 

The top icon (an “i”) provides basic information about any country.
The  second icon (a small scroll) provides information about diplomatic status such as treaties and wars.
The third icon (a small document) provides information about  relationships,--a measure of hostility or friendliness.
The fourth icon (coins) provides information about trade and exports.

To obtain any particular fact, two clicks may be required. One click to choose among the four icons--the type of information sought; and a second click on the map to choose the country that you are interested in.  

Alternatively, if you are interested particular facts (such as exports, or relationships) of several countries,  select the appropriate icon first, and then click on the countries on the map in succession.
