Question

how do you access the style window to create a new cell style?
home tab --> styles section --> cell styles --> new cell styles
home tab --> alignment section --> merge & center
page layout tab --> arrange section --> selection pane

Explanation:

To create a new cell style, you access the Style window through the Home tab. In the Styles section, you click on Cell Styles and then select New Cell Styles. The other options (Home tab -> Alignment section -> Merge & Center is for cell alignment, and Page layout tab -> Arrange section -> Selection Pane is for managing objects on a page) are not related to creating new cell styles.

Answer:

Home tab --> Styles section --> Cell Styles --> New Cell Styles
