While standardization can be neat, you run into problems with different keyboard layouts around the world. For instance '/' is Shift-7 on my Nordic keyboard.
Indeed this is an issue many of the keyboard libraries etc have. US keyboard layout is usually the default but it's pretty much a minority keyboard layout in the wild.
Then there's also the differences with windows and osx keyboard layouts.
If you can solve these issues with this library, then it would be really awesome!
