I second looking through xunicode.sty. Most of the tipa commands are the same, although a couple were altered, as precedence was given to the math symbols (I think). The comments in file explain why a particular command was assign to a particular character in these cases, and IIRC, tell you what command has been assigned to an alternate character.
Once you find the commands you want, you can use TexMaker and create a palette of characters that you use most often. Or you can create a custom keyboard layout with dead keys to input the characters (we distributed one such keyboard for a project once, aside from Windows throwing a security dialogue, we didn't have much trouble with it). -Andy -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
