How to Change Case in Microsoft Word (The Built-In Shortcut)
While this online tool allows quick conversion for web documents, emails, and code, Microsoft Word actually has a built-in keyboard shortcut to change case without retyping:
| Platform | Keyboard Shortcut | What It Does |
|---|---|---|
| Windows | Shift + F3 | Cycles selected text through: lower case → UPPER CASE → Title Case. |
| Mac | fn + Shift + F3 | Toggles letter casing on macOS Word versions. |
| Ribbon Menu | Home Tab > Font Group > Aa button | Opens Word’s drop-down menu for Sentence case, lowercase, UPPERCASE, Capitalize Each Word, and tOGGLE cASE. |
Case Formatting Styles Explained
- Sentence case: Capitalizes the very first letter of each sentence while keeping all other letters in lowercase, following proper grammatical punctuation.
- Title Case: Capitalizes major words while keeping conjunctions, prepositions, and articles (e.g. in, the, of, for, with, and, but) in lowercase, matching editorial style guides like APA and Chicago.
- UPPERCASE: Converts every single character to a capital letter. Ideal for headlines, legal disclaimers, acronyms, and warning callouts.
- kebab-case & snake_case: Replaces spaces with hyphens (
-) or underscores (_) in lowercase. Essential for naming files, URLs, and code variables.
