How to type dʒ symbol (IPA) on Mac? I want to type in dʒ on macOS but I don't know how I can type it. I tried ⌥ + keys but it seems that none of the keys is mapped to the symbol. It's not listed on this page.

I use the US Extended keyboard: So how can I type this symbol?
With ABC (formerly US) Extended, ʒ is made by typing option-shift ; and then z.

In general, to see which key does what, use Keyboard Viewer.

More info about ABC Extended can be found here. And here.
