I think you misunderstood. The [ ] were meant to indicate the little box in which cross-references are set off in InDesign.

I tried all 7 options given in the Windows forum (https://www.tenforums.com/tutorials/5507-default-apps-choose-windows-10-a.html#option1) but CC 2017 didn’t show up on any of them!

I tried several experts and corresponded with Adobe about the problems with their epub creations, and they admitted they could not handle what Kindle can. What’s so hard about them restoring the Kindle plugin, especially if it weans people off CS6?

If you don’t know what rubi are, you may not want to bother with my problem. (They are the characters set over Chinese characters as a phonetic guide.)
