The Effects button on the toolbar and the Effects... option on the Style menu enable you to alter one or more attributes and apply the new settings to the selected area of text. To do this:
Select the area of text you want to apply effects to.
Click the Effects button or choose Effects... from the Style menu.
The Effects dialogue box will appear. It is like the Style dialogue box for the style currently applied to the area you have selected; but all the entries are greyed out until you click on the attribute you want to change.
Click on the entry for the attributes you want to change, and make the required changes as if editing a named style.
Click OK in the dialogue box. The attributes you have chosen will be applied to the selected area.
