Add or remove border vertical interior

Windows shortcut 

On Windows, this shortcut only works within the Format Cells dialog box, on the Borders tab. If you use this shortcut in Format Cells, you'll see a interior vertical border added or removed from the border preview area.

There is no equivalent shortcut on the Mac

I just wanted to say thank you for the useful tutorials...This info is really useful for me at the moment because I'm just starting my first job while I'm not yet graduated from college. -Andrea
