-- Dwm-like swap function for xmonad.
|
|
--
|
|
-- Swaps focused window with the master window. If focus is in the
|
|
-- master, swap it with the next window in the stack. Focus stays in the
|
|
-- master.
|
|
--
|
|
-- To use, modify your Config.hs to:
|
|
--
|
|
-- import XMonadContrib.DwmPromote
|
|
--
|
|
-- and add a keybinding or substitute promote with dwmpromote:
|
|
--
|
|
-- , ((modMask, xK_Return), dwmpromote)
|
