===ACPI Hotkeys===
#REDIRECT [[acpid]]
There are many guides on how to configure multimedia hotkeys using program such as xev or keyTouch.  However, this guide explains how to use the simple utility of acpi_listen and generate your own script for hotkeys.
====Who Should be Using This Guide====
This guide assumes that you know your keyboard signals through acpi.  If you do not know whether or not this is the case, I suggest looking:
-[http://gentoo-wiki.com/HOWTO_Use_Multimedia_Keys|Using Multimedia Keys in Linux]
-[[Extra Keyboard Keys|Extra Keyboard Keys - keyTouch]]
====Installing Necessary Tools====
You should already have these tools installed, but just to make sure you will need
sudo pacman -S acpi acpid acpitool
[[ACPI modules|Refer to this guide]] on what modules you should load (i.e. through /etc/rc.conf or modprobe)
====Using acpi_listen====
Under root, or with sufficient access to the input devices, run:
If pressing a special key, such as previous or next, receives a response that looks similar to:
hkey VALZ 00000000 00000b31
then all is well and we can continue.
====A Sample Script====
As keyTouch and other keyboard programs did not work for me, or did not work effectively, I needed to create my own script that runs in the background and reacts directly from the output of acpi_listen.  Here is the script, feel free to use it / modify it to suit your needs and post suggestions on how it can be improved.  Currently, it is setup for a Toshiba Satellite A50 laptop to control exaile, but can be modified very easily for Amarok, Xine or other non-music related functions (internet, email).
i=`acpi_listen -c 1`
case "$i" in
"hkey VALZ 00000000 00000b31")
#echo "PREVIOUS"
exaile -p
"hkey VALZ 00000000 00000b32")
#echo "NEXT"
exaile -n
"hkey VALZ 00000000 00000b33")
exaile -t
"hkey VALZ 00000000 00000b30")
#echo "STOP"
exaile -s
#echo "ELSE: $i"
if [ "$e" != "1" ]
./myHotkey.sh &
Note:  This does not need to be run as root if you can receive an acpi_listen response from a user account (again, meaning you have access to the input devices).
