Dell Inspiron 17R laptop keyboard

Greetings,
My laptops keyboard is a special one with up to five characters on a key. I can access the keys in normal mode with no problem but I can't access the extra characters. I have tried different key combo such as ctrl shift and many more
to no avail. Does the keyboard language choice have anything to do with it?

Appreciate the help

Norm

Have you tried the Fn key?

Definitively with effects. I have run accross this link which has exactly the same characters. Tried the suggestions. No go.
