The Actions List shows three different types of information. Tools (Line, Circle, etc.) are shown in red. Points are shown in blue inside each tool. These are the geometric data used for each tool. Commands are shown in green; these include non-geometric actions like zoom or redraw. 
You can double-click on any object in the Actions List to repeat the command or input.
The icons below the Actions List control what is displayed there. The first icon can be used to show or hide the Actions List. 
The other icons can be used to hide the tools, points, and commands. 
The Recent Commands icon displays the tools last used, in reverse order. You can select one of these to activate it. 
The Recent Input icon displays a list of points entered. You can select one of these to use it for the current tool.
