Ah, that was much easier than I’d thought it would be. No further configuration needed - the script just works perfectly. Thanks very much!
Hello Bchend, I’m new user so may be I miss something but when I select some text before invoking Hookmark, I only get a hook for my MS word document, not a deeplink on the selected text. (my system is in french, I don’t know if it can be related).
If you can provide any help, or anyone else of course it could be great ! Thx 
Edit : found it (OK chatgpt found it..) you have to save your MS word document after the hook link creation. I let my post in case it can help someone else in the future.
Thank you for letting us know, and great job figuring this out on your own!
