I changed all my age shortcuts as you described above but now when I type yo; I get nothing, not a space, not a blip, not a letter. I have no idea what I could have done wrong all I did was c&p what you posted. Has this happened to other users?
With decimals, I just can't switch glossaries so much within the same document, and I don't want to rely on autocorrect for fear I should change employers and platforms and then be out of luck having to learn yet another new system. I guess I'll just have to turn auto spacing off but that's frustrating.
