A very short one liner straight from the manual – just to save me remembering where I put it! The keyboard layout use by the console is selected by the language environment variable.
Where <language_code> is one of the following:
|0||No Language||40||Français (Suisse Romande)|
|30||Dansk (Danish)||42||Italiano (Italian)|
|32||Deutsch (German)||44||Nederlands (Netherlands)|
|3C||Français (French)||4E||Belgisch-Nederlands (Dutch)|
