You must have Openbox (and possibly ObConf) already installed to use this guide.
To use Openbox with XFCE, log into your normal XFCE session. Then, run these commands in a terminal:
killall xfwm4 ; openbox & exit
(more...)
This allows you to bind your ‘windows’ key to the desktop right-click menu or middle-click menu, for example.
By default, the windows key is considered Super_L, a modifier key. Therefore you’d have to bind a command to windows+[some_key], which is not what we want. So what you want to do is re-map your windows key so that it’s not a modifier. The easiest way to do this is to use xmodmap like so:
xmodmap -e “keycode 227 = Menu” &
(on older versions of xfce it will be xmodmap -e “keycode 115 = Menu” & )
“Menu” above specifies that when you press the windows key, it will pop-up the app’s menu. We will later overwrite this to pop-up an Xfce menu. The 115 above is the keycode for the windows key. It should work for most people, but you can verify what it is for you with xev.
Now that you’ve changed your windows key to Menu, you can use it with one of the following shortcuts:
xfdesktop -menu <– pops up the right-click menu
xfdesktop -windowlist <– pops up the middle-click window list
If this all works out for you, you may wish to put the xmodmap command in your .xinitrc or .xsession file so that it will execute on startup.
