Hi,

I'm looking to deisable CTRL+ALL+F11 and F12 keys
My system : Debian 8 width LXDE

I wouldn't disable any of those keys because they are useful. Aside from that, when I want to change a key function I do a Net search. I don't remember anything I can easily look up. What you are looking for is not Debian specific. For example, I use setxkbmap -option caps:none to null my caps lock button as I tend to fat-finger it and have capital letters all over everything. So, go here.

what do those keys do? why do you need to disable them?
(i'm obviously a bit wary to test that now)
if you are sure you need to disable them, you can "mask" them with a hotkey (openbox has that built-in, see if 'obkey' is installed) doing nothing.

I need to re-affect these key :
Ctrl-Alt-F11 must reboot
Ctrl-Alt-F12 must halt
