OP; putting this question up because other Quorans have envied me my access to the IPA.
I have the following six keyboard layouts installed on my Mac:
- Greek Polytonic (GreekKeys)
- Greek Monotonic
- IPA-SIL
- Russian Phonetic
- ABC Extended (former US Extended)
- Australian
ABC Extended gives me all the Eastern European diacritics as well as the Western. Australian gives me the extended punctuation signs I’m more familiar with from two decades of Mac use: ¡™£¢∞§¶ †°±«»… And because… Straya!
