Icon – A file to use for the icon. Your own or have a look in the /usr/share/pixmaps/
directory for something suitable.

Requested Update:
for other keyboard letters (eg. è,é,etc...), get a virtual (onscreen) keyboard:
First thing to do:
Second you will need to update your repositories:
An upgrade to the whole system isn't needed but it is recommended:
Now we can install the virtual keyboard (matchbox):
sudo apt-get install matchbox-keyboard
Rebooting is recommended:
Now you can access the keyboard:
MENU >> ACCESSORIES >> KEYBOARD

If the keyboard isn't visible in the menu you can enable it by going to:
MENU >> PREFERENCES >> Main Menu Editor
There you will be able to enable the keyboard.
If everything has gone perfectly you will now have an onscreen keyboard.
