Description of problem:
Most new keyboards have tons of multimedia keys, all working in "their own
way"(tm), meaning with different keycodes. It was easy when there were only
84/101 key keyboards, now every laptop has tons of these extra keys.
  
Actual results:
There's no "proper"(tm) way to set up multimedia keys.

Expected results:
system-config-keyboard should offer an uniform way to setup multimedia keys.

Additional info:
The task can be done in two steps:

  1. using setkeycodes setup the kernel's key map
  For this step looking at /var/log/messages almost always gives what one needs.
showkey -s should be helpfull, but I can't figure out where's the key code
(anyone?).

  2. using xmodmap (/etc/X11/Xmodmap) setup X11
  xev gives me all the info I need to set this up.

What about an additional interface to system-config-keyboard that offers the
user to press every extra key he/she has and secify what this key should do
(volume up/mute/down...).

BTW: A global (text + X11) way to choose how to switch the keyboard layouts
would be nice too (alt+shift, ctrl+shift, both shifts...). I currently do this
by custom keyboard map (text mode) and xorg.conf's options.

PP: setting alt+shift to work with 3 keyboard layouts (US,BG-Phonetic,BG-BDS) in
X11 does not work, Win+shift/Win only however does.
