Ok, plenty of misunderstandings in this thread. Thank you for the clarification.

Well, I ended up with a solution so I'm not calling anything discussed here a catastrophe.

But as far as "as unusual as the case in point", I have my left fourth finger close to Ctrl, and my right fourth finger close to [ and ], so what better combination could I think of when I need something that goes to the left and then to the right ? That might not occur to you because of your background, but for me, that binding was just urging me to be done...

Thank you !
