Disabling an xfce4 keyboard shortcut
I am new to xfce (version 4.4.1).
How can I disable an xfce key shortcut assigned by default? I want to leave Alt-Space for a very frequently used work in emacs, but now when I press it, I get an xfce window menu. How can I "pass" the key-press to the application (emacs)?
Thanks in advance.
