What I find VERY surprising is that it seems (as indicated by the italicized portion of the quote below) that they have completely overlooked the option to double click the format painter button to apply formatting repetitively.
Just an interesting observation and a seemingly strange error on a blog post?!
Copy and paste formatting
If you want to format an object to look just like another object without reapplying all of the formatting by hand, use the formatting clipboard. Select the object whose formatting you want to copy and press Ctrl+Shift+C. Then, select the objects that you want to have the same formatting and press Ctrl+Shift+V to paste the formatting. This also works on the slide thumbnails if you have a slide background or theme that you want to copy from slide to slide.
This keyboard shortcut makes use of the Format Painter feature, which also allows you to copy formatting from one shape to another. The keyboard shortcut is a good one to remember since it packs even more power—once you’ve copied the formatting, you can paste the formatting onto as many shapes as you like without having to copy it again.
