Ah okay... I should have carefully read: If it says "key binding" it  
means "key" of "keyboard", not of "mouse" :)

Oh, all of the above are very interesting question, but I guess this  
will be quite a piece of work, because I then have to reinstall 8.04,  
get it working and then upgrade again. My question here is: Is this
