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.
