Uppercase wording example

3. When describing writing, case describes the capitalization state of text characters. For example, when letters are uppercase, they're all capitalized, and lowercase has no capital letters.

How to change the case

To change the case of a letter, press and hold down the Shift key, then press the letter you want to be capitalized. Or, turn on the caps lock feature by pressing the Caps Lock key to make all letters capitalized.

What is sentence case?

Sentence case is the capitalization of the first word of the sentence with all other letters being lowercase, like this sentence. If the sentence contains proper nouns (names, companies, and places), titles (e.g., books, magazines, and movies), or acronyms should be properly capitalized.
