Getting special keys to work

[John Hupp]

The next problem is that Fn-F4 and Fn-F5 don't generate any keysyms, so 
they can't be bound to the commands suggested by Andre.

To deal with that, I've been following the In-Depth Instructions in 
https://help.ubuntu.com/community/MultimediaKeys, and I have identified 
the scancodes and picked a couple unassigned kernel keycodes, but that 
article is old, and writing setkeycodes commands into 
/etc/init.d/bootmisc.sh or /etc/rc.local seems deprecated (those files 
don't exist).

Is there more current documentation for this task?  Is ibus-setup 
supposed to handle this job somehow under Lubuntu 14.04?  Or is there 
another place preferred for auto-starting setkeycodes commands?
