bracket not working with french keyboard

Hello

I use an English version of After effect ( I prefer) and I have a french keyboard. I can say it works great all the time but I still can't use the [ ] bracket.

In the french Keyboard it is Alt+shift+(      ( Left parenthesese is on the 5 key ).

When I type Alt+shift+[ on After It happen nothing??

If I swith to american language Alt+[ it works fine.

I don't understand

I someone in the same configuration could help me

Thank you
