====== Compose Key ======

Having a compose key is sick. Why have I only just found out about this.

I us the US keyboard layout, so doing accents has been a pain. Either you memorise a bunch of unintuitive strings of characters, or you copy+paste.

Compose key to the rescue! I use ''setxkbmap -option compose:ralt'' to make the right alt key the compose key, and now I can enter accents and other useful unicode characters with very sensible key sequences.

You can add sequences with the file ''~/.XCompose'', or by using the environment variable ''$XCOMPOSEFILE'' to put it somewhere else (also might wanna set ''$XCOMPOSECACHE'').

Like lots of keyboard meta keys it has a [[unicode]] character you rarely see: ⎄

===== Sequences =====

Some one's I've found useful

Press [compose key], then the indicated sequence of keys
