How does one type an "É" (capital e acute) in the French keyboard layout in Mac OS X?
French layout?


Press caps lock ⇪.
Press the é key (that's the 2 on a QWERTY).
Press caps lock ⇪ again.




But you need to make sure you're using the French layout, and not French - numeric (“Français - numérique”, French flag with “123” beneath it). 



Otherwise, you're explicitly asking the system to use the caps lock key as a shift lock for the numbers bar on the top of the keyboard!
