Hi. Using ID 19.2 under Win 11. My question was partially answered by Peter Kahrel here (it was something of a revelation): https://community.adobe.com/t5/indesign-discussions/is-it-possible-to-convert-index-numbers-in-indesign-to-a-form-other-than-numbers/m-p/14448620#M563505 But my question goes just a little further into EPUB, and I'm hoping for advice from the community. Summary: Like the OP of the linked post, I would like to use an InDesign index in an EPUB. Peter Kahrel ably showed how to use GREP to replace the numbers in an ID index with a string (I used "Go") that maintains the link to the target location, thus allowing a non-page-specific index link to an index target location. This works (great) for PDFs, but does not appear to work in EPUBs, although I can see it work in the Calibre EPUB editor. I'm obviously missing something (mea culpa!) Detail: (This is a duplicate of my question asked 'way down on the OP posting above, hate to ask it twice but I'm not sure how soon anyone might see it.) My question: Summary of problem: The eventual EPUB created using the GREP substitution method does not appear to link from the Index to the instance, and I'm not sure how to figure this out/debug. I am aware that EPUB is a set of zipped HTML docs. Details: I created an InDesign book with two documents; call them targets.indd and index.indd. In targets.indd, there are three pages, each containing a single item; this, that, and the other thing. I created a normal index, which showed the three items and their respective page numbers. I tested this by creating a PDF, and the ID links from the index to the target were in place and worked. I ran the Peter Kahrel's GREP, and replaced each of the page numbers with the word "Go." I tested this revision by creating a PDF, and the ID links from the index to each target still worked (this is great!). I created an EPUB version of the doc. This is where I began to have trouble. In ID, Window | Interactive | EPUB Interactivity Preview showed the target pages and the index page as expected. While the EPUB previewer gave me a finger "pointer," clicking the word Go in the index did not take me to the target (no reaction). I opened the EPUB in Calibre editor (not an Adobe product; I know). In Calibre, clicking the word Go took me to the target -- so as far as the HTML was concerned in Calibre, this arrangement works. I opened the EPUB in Kindle Previewer 3.78 (just downloaded today; not an Adobe product, I know). The Kindle Previewer displayed the three target pages and the Index as expected, but clicking Go in the index did not take me to the targets. There was no reaction to the click. Just like the Adobe EPUB previewer. So in both the Adobe EPUB previewer and in the Kindle EPUB previewer, the index links did not work. But in both PDF and in Calibre, they did. I am puzzled why the links appear to work sometimes but not others. I am sure this is because I am missing something that I otherwise should know. The GREP works just fine... except I don't end up with an index usable in EPUB. Any advice? PS: It may be that Kindle cannot handle an index even though it is made up of unnumbered target links. I can live with that, but want to make sure I'm not simply doing something incorrectly or missing a simple setting. Likewise, it may be that ID's interactive EPUB window won't deal with indexes. I can live with that too, with the same proviso. But Calibre works as expected.... Thanks as always to the community. -j
