If you find yourself applying the same formatting over and over again, then you should familiarize yourself with the Format Painter tool. The Format Painter copies how text or objects are formatted and lets you apply that formatting elsewhere.
The formatting is copied to the painter tool. The cursor changes to a paintbrush to show that it is now in Format Painter mode.
Select the unformatted text.
The formatting is applied. The Format Painter then turns off, meaning, to apply the same format to more text, you have to repeat the whole process all over again.
You can also use the Format Painter to copy the formatting of objects, such as shapes, and apply that formatting to other objects.
