Keymap

A keymap is the mapping of a key press on a keyboard, and the character that gets inputed. By changing keymaps, we can change what letters a keyboard inputs. This is useful in internationalization, but also to change the layout of the keys. US style keyboards use the QWERTY keyboard layout, a common alternative is the DVORAK layout, to change layout you have to change keymaps.
