rx9111ns, I clearly misunderstood you. I just definitely disagree with you about your "ferrari / citroen" comparison and I didn't want to let that sentence unanswered.
Having 10 or 10000 posts doesn't change anything : it's just that usually, trolls doesn't come from low-posts-number people, because they usually don't want to be perceived as troll-maker.
PS : Of course I remember the C-key. I used Blender before that time (release 1.8 )
