[xmonad] A few issues with xmonad I'd like to fix

[Laurent Humblet]

Hi,

Thank you for your help on fixing the various issues I had with xmonad. 
  Sorry I didn't send this email sooner.

I have applied your code and it fixed the _very_ annoying regular crash, 
that really did help so thank you again particularly for this :)

I'm still stuck with the xK_section and xK_exclam keys and I'm 
requesting help here again.  The issue I have is simple: I have a really 
hard time understanding the haskell config file.

Here is my config cleaned up a bit: http://pastebin.com/rxbLXaX5 and the 
following line is where I'm stuck:

	, keys = \c -> azertyKeys c `M.union` keys defaultConfig c

Here is what I'd like: set/create at the start of my config 3 distinct 
key bindings in 3 different vars:

	- custom keybindings for the 'sendMessage (JumpToLayout "Tall")' for my 
layouts shortcuts (myLayoutKeys)
	- azerty config (azertyKeys - use the existing xmonad one)
	- custom keybindings for xK_section and xK_exclam (myAzertyExceptionsKeys)

Then I'd like to put it all into one var called myGlobalConfigKeys and 
add it to the main xmonad setup in xmonad.hs :

	xmonad $ defaultconfig
		{
		...
		, keys = myGlobalConfigKeys
		...
		}


So I'm looking for a very simple sample on which I could keep on working 
on it alone.

Sorry for asking this which might seem fairly straightforward but I have 
a very hard time understanding the config file.

To really understand it, I believe that the best would be for me to be 
on voice coms for about half an hour with someone who understands it 
well to talk through the config itself.  I can also learn haskell which 
I would love to do if I have some spare time but it's not the case at 
the moment.  I did the website tutorial but it's still not clear enough 
for me at the moment.

Thank you once again for your help,
Best regards,
Laurent
