Programing a computer keyboard to shake?

I need to punch in ö ë ä and SS. Charmap Alt codes and not doing that to me. Running Windows Vista, there is a way to configure it with a U.S. keyboard? I was hoping that if I charged it out as one, as E and so on.

Hello this is a way side .. the way is not true, but if you have not found one way you can use full for you if space so that you type in the text, such as work or programming that you can enter xo: ö .. x: ë .. xa: a .. xB: SS and then replace all xo, x, Xa, with the original lyrics that you bring ALTCodes be happy
