Attached is a revised version. Hope it is clearer now.

OK, I agree. Let me know if you want the document in another format.

Using infrared remote controls with Rosegarden
==============================================
Rosegarden can use infrared remote controls for some functions like transport
buttons and track navigation. At a low level, support for infrared remote
controls is provided by LIRC (Linux Infrared Remote Control). There is a daemon
named "lircd" that serves messages from the IR remotes to client aplications.
You can find more information about LIRC in their web site at
http://www.lirc.org
At a higher level, KDE applications may use an application named IRKick (the
KDE LIRC Server daemon) to manage the remote control behavior when used with
KDE applications. Using this program, KDE applications can receive LIRC
messages without needing to be implemented explicitly as LIRC clients. You can
find this program in your Linux distribution as a package named "kdelirc", or
belonging to "kdeutils".
Rosegarden has both an internal LIRC client, that can be optionally compiled
into the program, and also has support for IRKick. The internal LIRC support
may be useful when you don't use the KDE desktop with Rosegarden, or when you
don't want to use IRKick. If you already use an infrared remote control with
other KDE applications with IRKick, you may use also Rosegarden in the same way.
LIRC Daemon Setup
-----------------
First, it is necessary to install and configure the LIRC daemon. See
http://www.lirc.org/html documentation to find information about how to
configure the lircd daemon. The details are different depending on the infrared
receiver that you use, and the remote control model.
As an example, here is the howto for a modern digital TV USB receiver:

LIRC Client
-----------
If you want to use the internal LIRC client compiled into Rosegarden, you need
to provide a configuration file. It is usually located in your home directory
with the name ".lircrc", and here is where you define the bindings between the
remote control buttons and the application functions. Here is an example of
such configuration.
# ----------------------------------------------------------------------------
# lircrc.rosegarden
#
# Example .lircrc config file for rosegarden.
# Adjust the "button =" lines to your remote control in your ~/.lircrc
# ----------------------------------------------------------------------------
begin rosegarden
# ------------------------------
# rosegarden transport
# ------------------------------
begin
prog = rosegarden
button = FORWARD
config = FORWARD
end
begin
prog = rosegarden
button = REWIND
config = REWIND
end
begin
prog = rosegarden
button = PLAY
config = PLAY
end
begin
prog = rosegarden
button = STOP
config = STOP
end
begin
prog = rosegarden
button = RECORD
config = RECORD
end
# (mis-)use volume up/down for jumping to beginning/end
begin
prog = rosegarden
button = VOLUMEUP
config = FORWARDTOEND
end
begin
prog = rosegarden
button = VOLUMEDOWN
config = REWINDTOBEGINNING
end
# ------------------------------
# track navigation
# ------------------------------
begin
prog = rosegarden
button = CHANNELUP
config = TRACK-
end
begin
prog = rosegarden
button = CHANNELDOWN
config = TRACK+
end
# track LED's
begin
prog = rosegarden
button = MUTE
config = TRACK-MUTE
end
begin
prog = rosegarden
button = MENU
config = TRACK-RECORD
end
end rosegarden
IRKick support
--------------
The IRKick profile was already installed in your system when you installed
Rosegarden. You only need to start the IRKick program, and use the
configuration dialog to bind the buttons of your remote control to the actions
provided by Rosegarden. You may also bind a remote button to any Rosegarden
function exported in a DCOP interface.
You can find IRKick somewhere in your K menu. The exact place depends on your
KDE distribution and version, look at System/Desktop Applet or
System/Configuration.
Once you have both LIRC and IRKick running, you need to bind the remote control
buttons to Rosegarden actions. To do so, use the "Configure" dialog, which is
also available as a KControl module. Press the "add..." button to open a
wizard. The first step is to select Rosegarden in the applications list. Next,
choose a remote control button name, and press next. Then, select the function
which you want to perform with the remote control button. The last page allows
to select some options. You can repeat the procedure for each button, but you
don't need to use all of them.
