Alt text as searchable content in PDFs
Would love for alt text to be part of the searchable text in Acrobat's "Find" function—whether that's alt text that's been added in Acrobat as a tag or has been set up prior in another program (like INDD).
Thanks for connecting with us. We have taken you suggestion and we have kept it in our radar. Currently we do not plan to implement it in near future but you may see it coming in future releases.

You can easily see this if you use the Set Alternate Text tool in the Accessibility Toolset. It allows you to cycle through everything that should have alt-text to see what the entries are.
