Remaping the combination <Super> + W (Ubuntu 14.04)

[gucor]

By default this combination causes the Windows Spread (https://www.youtube.com/watch?v=f2tS9tfnZqU). Is it possible to change this combination on clicking on one button <Super>?

I don't know how affective it would be, or if it will break anything, but in the program compizconfig-settings-manager(ccsm, for short) you can change the default super key in ubuntu unity plugin > launcher, and you can change the super+w key in scale > bindings.

Like I stated, don't know what will happen, but there it is.
I would personally keep the ccsm window open until I felt comfortable that the new combo worked right, so I could revert it back if problems arise.
