Where is the tilde on the AZERTY (French) wireless keyboard?

Hello,

I'm working on a MacBook Air (late 2011 model), along with the Apple Wireless keyboard. The keyboard is a physical AZERTY (French) layout, but I change the mapping to US using the system preferences.

I work in the Terminal a lot, and I can't find the tilde (~) key. When I type where it would be on a US QWERTY layout, the output is the plus-minus (±) sign. When I type Option+N, I get the tilde accent character (˜). Terminal does not interpret the ~ and ˜characters the same.

My question: How can I enter the ~ character from the wireless keyboard? Currently, I reach up to the Air's integrated keyboard and type it there. Not exactly an ergonomic solution.

Thanks!
