You can copy the style of a section of text and apply the style to other text. Only the style of the selected text changes; the selected word or phrase remains the same.
Select the text whose style you want to copy.
Choose Format > Font > Copy Style.
Select the text you want to restyle.
Choose Format > Font > Paste Style.
You can also make copied text match the style of the text in the place where you paste it. Select and copy the text, and then choose Edit > “Paste and Match Style.” The pasted text loses its original style and takes on the style of surrounding text.
