Basic, basic formatting question

[Karen in CA]

I need to change the shading in multiple cells and in multiple worksheets. The grey shading default is 25% in the fill color menu. Is there a way to lighten the shading to 10%?

Click on Tools- Option, then the Color tab and the Grey box. Then click on Modify, Select the Custom tab and change the slider to the shade you require.
