-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Prompt
-- > import XMonad.Prompt.XMonad
--
-- in your keybindings add:
--
-- >   , ((modm .|. controlMask, xK_x), xmonadPrompt def)
--
-- For detailed instruction on editing the key binding see
-- "XMonad.Doc.Extending#Editing_key_bindings".
