The nslxIPA keyboard for Mac
Version 1.0 is now available!
The nslxIPA keyboard is designed for relatively easy and intuitive Unicode input of characters from the International Phonetic Alphabet directly from the keyboard, without having to use opaque codes or other windows to access the characters. Note that the nslxIPA keyboard is a Mac-specific keyboard layout; there may be ways of converting it for use on other systems, but it may not work as intended, if it even works at all.
The companion nslxIPAg keyboard is identical to the nslxIPA keyboard, except it has the keystroke assignments for <g> and <ɡ> reversed, so that the g keystroke on the nslxIPAg keyboard produces the ordinary non-IPA <g>, while the shift+option+8 keystroke produces true IPA <ɡ>.
The current version of the nslxIPA and nslxIPAg keyboards is 1.0.
I am open to suggestions from users who might find the keyboard easier to use with some minor modification, so if you have such suggestions, please let me know.
