Being a World of Warcraft player, I use keyboard combinations to cast spells and "alt + #" is one of the combination, # being the key just before the 1 2 3 4 [...], under "escape" and on top of "tab" (I have a "French(canada)" keyboard).

I've searched in the keyboard options, the shorcuts parts and I found nothing, I even tried to assign it randomly, hopping it'll overwrite the real shorcut but it didn't.

When I press "alt + #" I have a "alt + tab" like but just for one type of window. For exemple it'll make me navigate through many instances of folder, but it won't switch to another application. It just cycle through the open windows of one application.

Help me get rid of this annoying shorcut please ! Thanks in advance.
