External Cherry keyboard on Macbook Pro

Hi,

I've bought me a new macbook pro to develop on. Since it doesn't have a numeric, I bought me an 'Cherry keyboard'. Yet I can't get it to work. It is an azerty. I can type on it but 'special' keys like the @, \, €, ... are all on different places. I don't even find the [[ and ]], wich are highly needed to develop 🙂

How can I configure the keyboard ? I've tried different layouts but none work (be, fr, ...)

Also: I use an external screen. Is it possible to make that the Macbook Pro doesn't go to sleep when I close it, so it doesn't have to be open while I work?

Thanx!

Kind regards,

mtjs.
