Ctrl+Shift+C, Ctrl+Shift+V: Copy, Paste Format in Microsoft Word and PowerPoint
Try this one in Microsoft Word or Microsoft PowerPoint: Select some text that has some formatting you like. Hit Ctrl+Shift+C to copy the formatting into the clipboard (nothing visible will happen).
Now scroll elsewhere and select some different text. Press Ctrl+Shift+V. Now that formatting you had copied is applied to the selected text. Magic!
