Keyboard layout independent input

Is there a method to check for keys on the keyboard independent on the national keyboard layout?

To give an example: In Germany Z and Y are swapped, and we have an additional key left to the enter key for the # sign. That means, that KeyHit(KEY_Z) returns 'True' for me when I am hitting the US' Y-Key (I hope you get it).

I need to check the keys from Q to P in a row, and I don't know how to do that.

Thanks in advance!
