The Transformations menu lets you change the case of selected text. Want to change something to ALL CAPITAL LETTERS, without retyping it? Select the text, right- or Control-click, and choose Transformations > Make Upper Case. If you want to Capitalize A Bunch Of Words, you can do that, too: Transformations > Capitalize. And the Make Lower Case option puts all the selected text back into little letters.
These built-in text tools can save you a lot of time, while making your documents look better. And they aren't hard to use, once you know where they are.
