如何在xmonad中的密钥发布上设置操作？

sudo apt-get install xmonad

import XMonad.Util.EZConfig
import XMonad.Util.Run

main = xmonad $ defaultConfig
    { keys = \c -> myKeys c `union` keys defaultConfig c
    , handleEventHook = handleEventHook defaultConfig <+> fullscreenEventHook
    }

myKeys conf@(XConfig {XMonad.modMask = modMask}) = M.fromList $
    [ ((modMask .|. shiftMask, xK_p), spawn "xdotool key --clearmodifiers --repeat 1 --delay 100 shift+Print")
    ]

sudo apt-get install xdotool
