where is the '^]' character on an azerty keyboard?

I finally found it, to input the special character ^], and I insist on the fact that it is one character, on a Linux Ubuntu (may work on other distrib, does not work on windows) you have to press AltGR+Ctrl+]

] is on the key with those 3 characters : °)].

It will not work at all time, I know it works in telnet but on the terminal it prints nothing.

Two to the left of Backspace by the looks of it:

Edit

I've just read elsewhere that it's ctrl+$ on AZERTY, which makes sense as it's the same physical placement. (http://www.madrouter.com/pemu-pix-emulation-and-dynamips/ then ctrl+f "AZERTY")

On AZERTY keyboard type Control+5 :)!
