Typing the tilde '~' character on a PC keyboard I'm using my macbook pro with an international Spanish PC keyboard and am trying in vain to find the tilde '~' character. I've tried the layouts "British - PC" and "U.S. International - PC" but cant figure out how to get that tilde to show.

On the U.S. layout, when I press the key between left-shift and Z, I get the back tick '`'. When I use shift, I get '˜'. With the option key I get a back tick as well.

On the British layout, when I press the button below escape I get the back tick, but with shift I get "¬". With the option key I get '¦'.

Anyone know what I need to press?

In response to the possible duplicate:

The answer given for the question about the tilde with a Spanish keyboard does, indeed mention that you can use alt+n and then / to type the tilde on English layouts, but as Tom Gewecke pointed out, that is not true for all English layouts as the other question seems to suggest. The answers here are more specific and helpful.
On U.S. International - PC layout, press Alt-N and then Space
