Audio Volume hotkeys
If you are using LXDE, the following steps will get your Audio Volume hotkeys Fn-Right and Fn-Left as well as Fn-F6 to work.
First, you have to make sure that alsa is configured correctly. You can configure alsa using
# alsaconfig
Executing
# alsamixer
you can adjust the volumes to a convenient setting. Then, adding
@ alsa
to the DAEMONS section of your rc.conf, you can ensure that the values you just specified will be loaded on every startup. Finally, paste the following lines into the <keyboard>-section of your ~/.config/openbox/lxde-rc.xml file.
