XKB and Xmodmap
First, I must say that Linux (Unix) uses two approaches to configure the keyboard layout (they are both independent of each other): XKB and Xmodmap. XKB is an extension of X, many people say that it is better, but too robust and perhaps less understandable by beginners. Xmodmap is one of the oldest ways how to configure your keyboard layouts – a little easier approach, especially good for experimentation, but no only that.
