--- > import XMonadContrib.MouseGestures
--- > ...
--- > mouseBindings = M.fromList $
--- >     [ ...
--- >     , ((modMask .|. shiftMask, button3), mouseGesture gestures)
--- >     ]
--- >     where
--- >     gestures = M.fromList
--- >         [ ([], focus)
--- >         , ([U], \w -> focus w >> windows W.swapUp)
--- >         , ([D], \w -> focus w >> windows W.swapDown)
--- >         , ([R, D], \_ -> sendMessage NextLayout)
--- >         ]

--- This is just an example, of course. You can use any mouse button and
