Dead key and compose key definition

Here is a good definition of what is dead key and compose key that i found on wiki.linuxquestions.org :

If you press a ` and an e, you get an è. In this case the key ` is called a dead key because it is at first stroke dead. A bit more tricky is the compose key. Press the compose key and then type two keys, and both keys will be combined. E.g. type the compose key, then the comma, then c and the outcome is ç.
