Comment 2 for bug 1289962

Having the keybinds to move a window between monitors would only be used by a select number of people (myself included). I don't think that the keybindings themselves are important, rather having the feature available is.

I believe that the best way to implement this is to have the keybinds for it blank by default. So if a user needs that function they can set it up however they like. A majority of users will change a few of the default keybinds on a fresh install, and would just set it up however they like anyway.
