The info toolbar has no tools to run; as the name suggests, it shows information for the user about the currently running tool at the bottom of the main window. When a tool is selected, the info toolbar will display the tool's name and the following action the tool expects, like selecting the first, second, etc. point or selecting a vector vertex, etc.
In the given example, the New Shape Object tool is running, and the software expects the user to start extracting the points where the vertexes will be placed. If no tool is active, this info toolbar is blank.
