After much fiddling around, I finally discovered where the case-changing option in Word 2007 is. It’s actually in the Home tab, and I was searching all over for it. You’ll find it in the Font group, near the bunch of buttons that starts with Bold and Italic – it’s the button that shows “Aa”. And if you’re interested, the keyboard shortcut Shift+F3 still works in Word 2007 as in previous versions of Word.
This is great when you have a line of text when you want to quickly capitalise, or de-capitalise (is there such a word? :D) Alternatively, it’s great for headings that you need to perform sentence caps on quickly too. An absolute time-saver 🙂
