People who type a lot, such as those who use typewriters, use the shift key instead of the caps lock or shift lock keys unless they have to type many capital letters in a row. But there is also a neat trick you can do with the caps lock and shift keys: when caps lock is on, you can hold the shift key while typing and what you type will be in lowercase letters instead of capitals. This can be done on some computers, such as those running Microsoft Windows computers.
