Hi Larry! I'd be happy to help you with that.

To create a black filled-in circle in Microsoft Word, you can follow these steps:

1. First, insert the capital "O" shape by going to the "Insert" tab, clicking on "Shapes," and selecting the "Oval" shape. Then, draw the shape on your document.
   
2. With the shape selected, go to the "Format" tab and click on "Shape Fill." From the drop-down menu, select "Black" to fill the circle with black color.
   
3. If you want to change the outline color of the circle, click on "Shape Outline" and select the color you want.
   
4. Finally, to adjust the size of the circle, click and drag the handles on the sides of the shape.

That's it! You should now have a black filled-in circle on your document. Let me know if you have any other questions or if there's anything else I can help you with.
