2. Add an Accent Letter With a Keyboard Shortcut - Whether you use a Windows or Mac computer, you can type a keyboard shortcut in Google Docs for your accented letters. To use these combination shortcuts on Mac, type the first shortcut immediately followed by the second. For example, to type the capital letter O with its accent as shown above, hold Option+E at the same time, release both, then hold Shift+O together, and release both.
