How to configure and use Compose sequences in XFree86 4.3

[grant.mcdorman]

Introduction
XFree86 has several ways of entering special characters (such as accented characters or special punctuation). I'm going to show you how to set up one of them, compose sequences, for a US-style keyboard. (The other methods include third-level shift keys, dead keys and input methods.)

Compose Sequences
Compose sequences are three-key sequences used to enter special characters. A particular key is set as the compose key; you then press, in sequence, the compose key followed by two other keys to enter a special character. For example, pressing Compose, e and then ^ will produce ê (e accent circumflex). Note that you do not press all the keys together; rather, each key is pressed and released in turn. The full set of compose sequences for the ISO8859-1 character set [Latin1] is too large to include here: there are 108 unique characters that can be generated, and multiple sequences for each character, with a total of about 450 sequences. The listing of the compose sequences can be found in /usr/X11R6/lib/X11/locale/iso8859-1/Compose. They're designed to be reasonably mnemonic and flexible. The order is usually unimportant; that is, you can press the second and third key in any order (i.e. Compose,e,^ or Compose,^,e will both produce ê).

How to Set It Up For All Users
To enable compose sequences for all users, you'll need to edit two files. The first is /etc/profile, where you'll need to set the environment variable LC_ALL:
