There is, however, another shortcut worthy of being added to the standard list. It is Shift+F3, Change Case. The Change Case command, when invoked, changes the case of selected text. If all lowercase text is selected, it capitalizes the first letter of each selected word. If each of the selected words begins with a capital letter, it changes all the text to uppercase. And, if all the words are already uppercase, it then changes the selected text to all lowercase letters. It is worth noting that the Change Case command toggles between sentence case — the first letter of the selected range as capital followed by the rest in lowercase — and uppercase if the last character of the selected text is a period.
There is a menu command, Format > Change Case, which allows text to be converted by selecting an option from a dialog box that appears. The choices are: lowercase, uppercase, title case, sentence case, and toggle case. Of course, it is easier and faster to press the keyboard shortcut.
The Change Case command makes it possible to fix capitalization of text without the need to retype, which can save a lot of time. And saving time is always a good thing, whatever the case may be.
