You can type characters with accent marks, such as é.
Choose Apple menu > System Preferences, and then click International.
Click Input Menu, and then select the Keyboard Viewer checkbox.
The Input menu (it looks like a flag or character) appears immediately at the right of the menu bar at the top of your computer screen.
Choose a language from the Input Menu pane.
Click the Input menu, choose the language you want from the top of the menu, if necessary. Then click again and choose Show Keyboard Viewer.
The Keyboard Viewer shows the characters for the selected keyboard. (For example, if U.S. is selected in the Input menu, the Keyboard Viewer shows the characters on a U.S. keyboard.)
Press Option or Shift, or both keys simultaneously.
As you press keys, accent marks are highlighted in the Keyboard Viewer, showing you which keys to press to produce the highlighted character.
Depending on your keyboard, you may not need to press any keys to see some accents.
In the text where you want to add the accent, press the necessary keys, and then release the keys and press the key for the character you want to accent.
For example, to make an é on a U.S. keyboard, press Option-E (for the accent), and then press E (the letter you want the accent to appear on).
