To quickly reuse text, copy it from one location and paste it to another. You can also copy and paste just the style of the text to easily match text style to other text in your image.
Select the text you'd like to copy.
Note: If you want to remove the text from its original location, choose Edit > Cut instead.
Choose Edit > Copy (from the Edit menu at the top of your screen) or press Command ⌘ + C on your keyboard.
