Using Fill Format mode
This method is quite useful when you need to apply the same style to many scattered cells.
Open the Styles and Formatting window and select the style you want to apply.
Click the Fill Format mode icon . The mouse pointer changes to this icon.
Position the moving icon on the cell to be styled and click the mouse button.
To quit Fill Format mode, click the Fill Format mode icon again or press the Esc key.
When this mode is active, a right-click anywhere in the document undoes the last Fill Format action. Be careful not to accidentally right-click and thus undo actions you want to keep.
