Is necroposting OK here? Somebody might wander by looking for the same information, so:
What I'm writing is based on plain Openbox, but lxde should be similar if not exactly the same.
You might try setting keybindings in:
~/.config/openbox/rc.xml
or there is probably a very similar file specific to lxde which shouldn't be hard to find.
It may be a longish file. Search for "keybind" to find the right section, some keybindings you can use for models, etc. Always back up config files like this before editing them. Then edit cautiously. To make the new version effective, you can click "Reconfigure" in your menu if you have such an entry. If you don't, try enabling the openbox menu (I think if you right click on your desktop, that may be an option - I'm not certain - it's been a while since I used the full lxde or lubuntu as opposed to just plain openbox) and it is probably on there. If it isn't you can add a stanza like this:
Code: Select all
<item label="Reconfigure">
<action name="Reconfigure"/>
</item>
and "restart" the menu. If none of that works, try relogging.
Hope that helps anyone reading this. Be careful in any case, and extra careful if you are using the full lxde, because, as I said, my suggestions are based on plain Openbox which is a wee bit different.
