Change Capitalizations the Easy Way

Do you want to capitalize every word in a header, or reduce all-caps text to lowercase? Select the text you want to change, and press Shift-F3 repeatedly until the text looks the way you want. Each press toggles between lowercase, uppercase, “sentence case” (capitalizing the first word of a sentence), and, if you didn’t know the Caps Lock key was down and yOU tYPED tHIS, a “toggle case” option that gets it right. You can also do this from the “Aa” pull-down menu on the Home tab of the ribbon, in the Font region, but why bother when a quick keystroke or two can get it done?
