I'm particularly interested in how to access the character options on the numbered keys on the top row. Never seen a keyboard like this....it must be for foreign languages! After much trial and error, figured out you have to hold down the 'Alt Gr' key and strike the '2' to type '@'. Still cannot figure out how to type the pound sign or double quotes. urgh! Why hp? Why? Did you get a bunch of these for free and need to get rid of them?
