Newbie needs help

Greetings

My keyboard seems to have gone a little pearshaped as the ampersand no longer works. How do I reconfigure the keyboard or are there special keystrokes to get the ampersand?

Thanks

go to Control Centre (in the main “Computer” menu under System)
Keyboard
Layouts
click Add
choose your country/layout.

e.g. here in Australia we use a US keyboard layout
