From the "View" drop down menu select "Customize Toolbars and Menus"... in the window that opens select "Tool Bars and Menus" and below check the toolbar you want the 2 eyedroppers to reside on (I checked "Formatting") ... now go back to the top of this window and click "Commands" ... there are 2 eyedropper tools you will need ... scroll down to "Pick Up Object Style" and select it ... now click and drag it to the Formatting Toolbar (I placed mine to the right of the tools already there) ... next go back to the list below and scroll to "Apply Object Style" and select it and drag it to the Formatting Toolbar and place it next to the "Pick Up Object Style" tool (I place it to the right of the Pick Up tool) ...

Now that you have the 2 new tools in the Formatting Toolbar, it is a 4 step process. For example, to copy the color of one rectangle and place that color into another rectangle: (1) click on the "Pick Up Object Style" tool and (2) then click the rectangle whose color you want to copy. (3) Now click the "Apply Object Style" tool and (4) then click the other rectangle which you want to have the same color as the first. That's it!
