I spoke too soon. All the programs (rfkill, pm-suspend, pm-hibernate)
must run as root, and nothing I have tried so far has allowed these keys
to work as I intend.
I created /home/<user>/.config/openbox/toggle-wifi.sh with this content:
#!/bin/bash
if [ $(rfkill list wifi | grep "Soft blocked: yes" | wc -l) -eq 1 ] ; then
rfkill unblock wifi
zenity --info --text "Enabled wireless"
else
rfkill block wifi
zenity --info --text "Disabled wireless"
fi
And then:
chown root:root toggle-wifi.sh
chmod 4755 toggle-wifi.sh
I also tried inserting 'sudo command' in front of the rfkill commands in
toggle-wifi.sh, and I tried 'sudo command toggle-wifi.sh' in the
lubuntu-rc.xml command statement.

Though I'm no better than an Upstart hacker, especially with regard to

/etc/init/kb-keys-customize.conf with this content:

# Map key codes to the scan codes emitted by Fn-F4, Fn-F5, Fn-F12
description "Map Fn-F4, Fn-F5 and Fn-F12 kernel scancodes to kernel
keycodes"

start on local-filesystems
script
setkeycodes e017 128 e016 129 e018 130
end script
After rebooting, I found that 'xev -event keyboard' now reports that
Fn-F4, Fn-F5 and Fn-F12 are mapped to X keysyms Cancel, Redo and
SunProps, so I expect that I should be able to bind those keys in
lubuntu-rc.xml to Andre's suggested commands.

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?

Thanks, Andre, for all of those great tips.
I've been looking at the Exec lines in several versions of
~/.config/autostart/LXRandR-autostart.desktop (created when one
clicks Save in LXRandR) and thinking about how I could create
something that would cause Fn-F7 to toggle through the LVDS, VGA and
S-Video outputs, but your approach -- simply binding to LXRandR --
is a MUCH better idea!
And if I wanted to add the ability to extend the desktop instead of
mirroring it, I could install arandr and just bind to that instead.

On lubuntu-rc.xml I do:
<keybind key="XF86Display">
<action name="Execute">
<command>lxrandr</command>
</action>
</keybind>
*lxrandr* deals with additional monitors, you just enable them
an apply.
I'm not sure what commands you can execute to sleep and
hibernate, but you can control radio with *rfkill*. I'm not
sure if those commands really require root access, but on that
case you can do a: *gksu command*

Hope that helps! To test the shortcuts without restarting all
the system you can restart only openbox: *openbox --restart*

Hi,
you can use arandr to make a shell script to switch the
display to a
certain mode. Plug in the monitor and use arandr to make a
setup you
want, and save that. Then open your config file for
openbox and set
the keyboard shortcut for your display key (i.e. XF86Display)
to execute the
<command>
/bin/bash /path/to/scriptname.sh
</command>
while scriptname.sh is whatever you saved the setup as with
the correct
path.
arandr is a front-end for xrandr. So the script is
actually using
xrandr to modify your display settings.
I hope this helps.
