-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@ file:
--
-- > import XMonad.Actions.CycleWS
--
-- > , ((modMask x, xK_Down), nextWS)
-- > , ((modMask x, xK_Up), prevWS)
-- > , ((modMask x .|. shiftMask, xK_Down), shiftToNext)
-- > , ((modMask x .|. shiftMask, xK_Up), shiftToPrev)
-- > , ((modMask x, xK_Right), nextScreen)
-- > , ((modMask x, xK_Left), prevScreen)
-- > , ((modMask x, xK_t), toggleWS)
--
-- If you want to follow the moved window, you can use both actions:
--
-- > , ((modMask x .|. shiftMask, xK_Down), shiftToNext >> nextWS)
-- > , ((modMask x .|. shiftMask, xK_Up), shiftToPrev >> prevWS)
--
