While typing, you can modify the case of any text by pressing either the Caps Lock key or Shift key. If you need to alter the case of text that has already been typed, skipped to the convert the case section.

Capitalize everything that is typed

The Caps Lock key is a toggle key, which means when it is pressed, everything that you type is going to be in UPPERCASE until you press the Caps Lock key again. If you want to type in all uppercase, the Caps Lock key can be used. However, keep in mind that in many situations, typing in all caps is bad etiquette.

Capitalize one letter at a time

To change the capitalization one letter at a time, press and hold either the left or right Shift key, then press the letter you want to be capitalized. Using the Shift key is the most common method of creating a capital letter on a computer.
