I found these:
http://www.linuxplanet.com/linuxplanet/reviews/7039/1/Strictly speaking LXDE isn't a window manager but a desktop environment, using Openbox as a window manager (alternatively you can swap in other window managers). Openbox allows you to show the LXDE desktop menu on right-click (right-click on the desktop to edit this option). Unfortunately, once I turned this on, I couldn't find an option in the Openbox configuration editor to turn it back off! Still, it's a useful enough menu. It would be more useful, though, if it were easier to add applications to the Applications sub-menu. It seems that the only way to do this is either to edit /usr/share/lxde/openbox/menu.xml, or to copy that file somewhere in your home directory, edit it there, and change the reference in ~/.config/openbox/lxde-rc.xml. This isn't that hard for experienced Linux users, but it's not exactly user-friendly, and still less so as I had to dig around to find that out.
That's my problem.
Thanks.
