I successfully added Italian as a second input language for my keyboard. By using the Super+Space key I can switch from English to Italian. The icon in the menu bar indicates this. When I select the keyboard layout chart for the Italian, some keys have 4 letters on them.

I cannot figure out how to access any of these different options.

For example, looking at the keyboard layout, the o key has 4 letters: small o and uppercase O, and the same with a grave accent. How do I get the accented ones to be used?

    You access them via <AltGr> or <Right Alt> (with or without <Shift>). – Gunnar Hjalmarsson Apr 4 '18 at 21:19
  • Maybe you are helped by an Onboard keyboard in order to display what is possible to type. – sudodus Apr 5 '18 at 6:18

You need to use "level 3 select key" to access those characters. Usually the AltGr (aka right Alt) key is the level 3 select key. For the fourth character use Shift+AltGr.


If you only need accentuated letters you could also use the US international keyboard with deadkeys. There to get an ò you simply type first the backquote (accent grave), then 'o'. To get a backquote alone you type backquote followed by space.

  • Thank you for the response. The first answer using the right alternate key worked for me. – Tony Apr 17 '18 at 23:48
