I have assigned my middle click mouse button to the shortcut Super-W in Ubuntu 10.04, now I need to change this binding, but I can not remember how I did it...
I've not used Btnx,xbindkeys, this are not installed...
Have you seen this?
There's an app named xdotool in the question. Maybe you used that.
If not, then maybe you have used gconf-editor, as described here:
