US keyboard layout with Norwegian characters

This is a keyboard layout for using a US keyboard layout, and still have a way to enter ÆØÅ without switching back to a Norwegian keyboard layout.

Install

On Ubuntu:

$ sudo cp no_custom /usr/share/X11/xkb/symbols/
$ setxkbmap no_custom

Other distros might use the above path, or /etc/X11/symbols.

This will reset it back to your default keyboard layout when you reboot. To make it persistent see:

(Right) ALT + ' = æ
        ALT + : = ø
        ALT + [ = å
        ALT + SHIFT + ' = Æ
        ALT + SHIFT + : = Ø
        ALT + SHIFT + [ = Å
