-- $usage
-- You can use this module with the following in your Config.hs file:
--
-- > import XMonadContrib.NextWorkspace
--
-- > , ((modMask, xK_Right), nextWS)
-- > , ((modMask, xK_Left), prevWWS)
-- > , ((modMask .|. shiftMask, xK_Right), shiftToNext)
-- > , ((modMask .|. shiftMask, xK_Left), shiftToPrev)
--
-- If you want to follow the moved window, you can use both actions:
--
-- > , ((modMask .|. shiftMask, xK_Right), shiftToNext >> nextWS)
-- > , ((modMask .|. shiftMask, xK_Left), shiftToPrev >> prevWS)
--
-- %import XMonadContrib.NextWorkspace
