The graphical user interface to keyboard mapping provides both an extremely fast way of checking on which key combination a function can be found, and a powerful tool for customizing the keyboard for an individual user, group of users, or specific legacy application.
The physical layout is obtained from the keyboard driver, and thus adjusts itself to the national keyboard you are using. In this case a Norwegian keyboard. Note the ÆØÅ, the composing keys for accented characters, and that the right Alt key is an Alt Gr shift that selects the alternate graphic on the key tops.
You can save your custom keyboard layouts with logical names, and load one on start-up, or as needed. Saved layouts can be shared with other users. A range of industry standard layouts is included for your convenience.
