How to use Ink bottle and paint bucket tool in flash CS4

On the extreme right of the screen in flash CS4, in the main menu you will notice the paint bucket tool,

at the right bottom of this tool, you will see a triangle, when you click on this triangle you will get the ink bottle tool, Now lets just draw a circle with no stroke on the stage, so select a color, lets say red,  and turn the stroke off and draw a circle on stage, now draw another circle with no fill and only a stroke color selected, say blue on stage, lets say you have something like this on stage,

You can click on the ink bottle tool as shown in figure 1, select a color, lets say black and click on the red circle drawn, you will get a black stroke on the red circle drawn, similarly click on the paint bucket tool, select a red green fill and click on the blue circle drawn, you will find the blue circle with green fill in it, like you see below.

This is the difference between paint bucket tool and ink bottle tool.
