I understand that SE is pushing for localization and internationalization options.
Can we get an integrated IPA keyboard like this one for Hebrew in judaism.SE?
There is this bookmarklet: IPA Keyboard for Linguistics.SE
Add it to your browser as a bookmarklet. While on an SE page (maybe it only works on Linguistics.SE out of the box), press the bookmarklet. A little schwa will appear next to the "redo" button above the Answer text box. Press the schwa, and the IPA keyboard will appear somewhere on the SE page; when you click the characters, they appear in the answer bow. You can also use alt-a for ɑ, alt-a-a for æ, etc.
It does not work perfectly for me, but that may be my browser: I see only half of the keyboard. But give it a try.
