WORD: Scroll Between Caps

In WORD, there is a shortcut you can use when you want to change something you have already typed to either of these three options:

• ALL CAPS
• all small
• First Letter Capped

For instance, if I had typed a title line that read:

MY FIRST DAY

and I wanted to see how it looked with just first letters capitalized, I can see that by highlighting the text, holding down Shift and hitting F3 key (Sh+F3).  The text then scrolls between all caps, all small and first letter capped so I can change it easily to:

My First Day
