Thanks a lot. It works exept for one line:

    `, modMask = mod4mask`


The error message is the following:


    Error detected while loading xmonad configuration file: /home/jenia-xmonad/.xmonad/xmonad.hs

    xmonad.hs:13:38:
        Not in scope: âmod4maskâ
        Perhaps you meant one of these:
          âmod4Maskâ (imported from XMonad),
          âmodMaskâ (imported from XMonad), âmod1Maskâ (imported from XMonad)
    
    Please check the file for errors.

========================================================================
Lets me repaste the config file:    
    
    
import XMonad
import XMonad.Hooks.DynamicLog

main = xmonad =<< statusBar cmd pp kb conf 
  where
    cmd = "xmobar"
    pp = xmobarPP
    kb (XConfig {XMonad.modMask = modMask}) = (modMask, xK_b)
    conf = myConfig

myConfig = defaultConfig { borderWidth = 2
	                 , terminal = "urxvt"
			 , modMask = mod4mask <----------- here is the mistake
                         }
========================================================================

Can you tell me please how to fix this?

Thanks again for your kind help.
