How does one type circumflexes in El Capitan? After updating to El Capitan I discovered that I was no longer able to type circumflexes. Before I was able to enable the "International Extended" keyboard in settings. Now it seems to be replaced with "ABC Extended", which does not permit me to type circumflexes in the way that I was used to. How can I input circumflexes in El Capitan?
ABC Extended behavior has not changed from that of US Extended, you type circumflex via option 6 and then the base character.  Or the base character then option shift 6.
