#!/bin/bash
# List the X compose sequences available to generate the specified character.
# I.E. the keyboard key sequence to enter after the compose (multi) key or
# a dead key is pressed.
#
# This version has been heavily modified by me (David the H.). It is now
# bash-specific, reduces the need for external tools (only grep is needed),
# and can handle multiple inputs.
#
# Original script info follows. For the original version, go here:
# http://www.pixelbeat.org/docs/xkeyboard/
#
# Author:
# P@draigBrady.com
# Notes:
# GTK+ apps use a different but broadly similar input method
# to X by default. Personally I tell GTK+ to use the X one by
# adding `export GTK_IM_MODULE=xim` to /etc/profile
# Changes:
# V0.1, 09 Sep 2005, Initial release
# V0.2, 04 May 2007, Added support for ubuntu
